In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Intel: hda-dai: Ensure DAI widget is valid during params Each cpu DAI should associate with a widget. However, the topology might not create the right number of DAI widgets for aggregated amps. And it will cause NULL pointer deference. Check that the DAI widget associated with the CPU DAI is valid to prevent NULL pointer deference due to missing DAI widgets in topologies with aggregated amps.

In the Linux kernel, the following vulnerability has been resolved: HID: multitouch: Add NULL check in mt_input_configured devm_kasprintf() can return a NULL pointer on failure,but this returned value in mt_input_configured() is not checked. Add NULL check in mt_input_configured(), to handle kernel NULL pointer dereference error.

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_core: Disable works on hci_unregister_dev This make use of disable_work_* on hci_unregister_dev since the hci_dev is about to be freed new submissions are not disarable.

In the Linux kernel, the following vulnerability has been resolved: selinux: ignore unknown extended permissions When evaluating extended permissions, ignore unknown permissions instead of calling BUG(). This commit ensures that future permissions can be added without interfering with older kernels.

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix potential NULL pointer dereference in atomctrl_get_smc_sclk_range_table The function atomctrl_get_smc_sclk_range_table() does not check the return value of smu_atom_get_data_table(). If smu_atom_get_data_table() fails to retrieve SMU_Info table, it returns NULL which is later dereferenced. Found by Linux Verification Center (linuxtesting.org) with SVACE. In practice this should never happen as this code only gets called on polaris chips and the vbios data table will always be present on those chips.

In the Linux kernel, the following vulnerability has been resolved: tracing: Have process_string() also allow arrays In order to catch a common bug where a TRACE_EVENT() TP_fast_assign() assigns an address of an allocated string to the ring buffer and then references it in TP_printk(), which can be executed hours later when the string is free, the function test_event_printk() runs on all events as they are registered to make sure there's no unwanted dereferencing. It calls process_string() to handle cases in TP_printk() format that has "%s". It returns whether or not the string is safe. But it can have some false positives. For instance, xe_bo_move() has: TP_printk("move_lacks_source:%s, migrate object %p [size %zu] from %s to %s device_id:%s", __entry->move_lacks_source ? "yes" : "no", __entry->bo, __entry->size, xe_mem_type_to_name[__entry->old_placement], xe_mem_type_to_name[__entry->new_placement], __get_str(device_id)) Where the "%s" references into xe_mem_type_to_name[]. This is an array of pointers that should be safe for the event to access. Instead of flagging this as a bad reference, if a reference points to an array, where the record field is the index, consider it safe.

In the Linux kernel, the following vulnerability has been resolved: net: restrict SO_REUSEPORT to inet sockets After blamed commit, crypto sockets could accidentally be destroyed from RCU call back, as spotted by zyzbot [1]. Trying to acquire a mutex in RCU callback is not allowed. Restrict SO_REUSEPORT socket option to inet sockets. v1 of this patch supported TCP, UDP and SCTP sockets, but fcnal-test.sh test needed RAW and ICMP support.

In the Linux kernel, the following vulnerability has been resolved: mm/filemap: make MAX_PAGECACHE_ORDER acceptable to xarray Patch series "mm/filemap: Limit page cache size to that supported by xarray", v2. Currently, xarray can't support arbitrary page cache size. More details can be found from the WARN_ON() statement in xas_split_alloc(). In our test whose code is attached below, we hit the WARN_ON() on ARM64 system where the base page size is 64KB and huge page size is 512MB. The issue was reported long time ago and some discussions on it can be found here [1]. [1] https://www.spinics.net/lists/linux-xfs/msg75404.html In order to fix the issue, we need to adjust MAX_PAGECACHE_ORDER to one supported by xarray and avoid PMD-sized page cache if needed. The code changes are suggested by David Hildenbrand.

In the Linux kernel, the following vulnerability has been resolved: clk: mmp: pxa1908-apbc: Fix NULL vs IS_ERR() check The devm_kzalloc() function returns NULL on error, not error pointers. Fix the check.

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix removed dentries still existing after log is synced When we move one inode from one directory to another and both the inode and its previous parent directory were logged before, we are not supposed to have the dentry for the old parent if we have a power failure after the log is synced. Only the new dentry is supposed to exist. Generally this works correctly, however there is a scenario where this is not currently working, because the old parent of the file/directory that was moved is not authoritative for a range that includes the dir index and dir item keys of the old dentry. This case is better explained with the following example and reproducer: # The test requires a very specific layout of keys and items in the # fs/subvolume btree to trigger the bug. So we want to make sure that # on whatever platform we are, we have the same leaf/node size. # # Currently in btrfs the node/leaf size can not be smaller than the page # size (but it can be greater than the page size). So use the largest # supported node/leaf size (64K). $ mkfs.btrfs -f -n 65536 /dev/sdc $ mount /dev/sdc /mnt # "testdir" is inode 257. $ mkdir /mnt/testdir $ chmod 755 /mnt/testdir # Create several empty files to have the directory "testdir" with its # items spread over several leaves (7 in this case). $ for ((i = 1; i <= 1200; i++)); do echo -n > /mnt/testdir/file$i done # Create our test directory "dira", inode number 1458, which gets all # its items in leaf 7. # # The BTRFS_DIR_ITEM_KEY item for inode 257 ("testdir") that points to # the entry named "dira" is in leaf 2, while the BTRFS_DIR_INDEX_KEY # item that points to that entry is in leaf 3. # # For this particular filesystem node size (64K), file count and file # names, we endup with the directory entry items from inode 257 in # leaves 2 and 3, as previously mentioned - what matters for triggering # the bug exercised by this test case is that those items are not placed # in leaf 1, they must be placed in a leaf different from the one # containing the inode item for inode 257. # # The corresponding BTRFS_DIR_ITEM_KEY and BTRFS_DIR_INDEX_KEY items for # the parent inode (257) are the following: # # item 460 key (257 DIR_ITEM 3724298081) itemoff 48344 itemsize 34 # location key (1458 INODE_ITEM 0) type DIR # transid 6 data_len 0 name_len 4 # name: dira # # and: # # item 771 key (257 DIR_INDEX 1202) itemoff 36673 itemsize 34 # location key (1458 INODE_ITEM 0) type DIR # transid 6 data_len 0 name_len 4 # name: dira $ mkdir /mnt/testdir/dira # Make sure everything done so far is durably persisted. $ sync # Now do a change to inode 257 ("testdir") that does not result in # COWing leaves 2 and 3 - the leaves that contain the directory items # pointing to inode 1458 (directory "dira"). # # Changing permissions, the owner/group, updating or adding a xattr, # etc, will not change (COW) leaves 2 and 3. So for the sake of # simplicity change the permissions of inode 257, which results in # updating its inode item and therefore change (COW) only leaf 1. $ chmod 700 /mnt/testdir # Now fsync directory inode 257. # # Since only the first leaf was changed/COWed, we log the inode item of # inode 257 and only the dentries found in the first leaf, all have a # key type of BTRFS_DIR_ITEM_KEY, and no keys of type # BTRFS_DIR_INDEX_KEY, because they sort after the former type and none # exist in the first leaf. # # We also log 3 items that represent ranges for dir items and dir # indexes for which the log is authoritative: # # 1) a key of type BTRFS_DIR_LOG_ITEM_KEY, which indicates the log is # authoritative for all BTRFS_DIR_ITEM_KEY keys that have an offset # in the range [0, 2285968570] (the offset here is th ---truncated---

In the Linux kernel, the following vulnerability has been resolved: HID: core: Fix assumption that Resolution Multipliers must be in Logical Collections A report in 2019 by the syzbot fuzzer was found to be connected to two errors in the HID core associated with Resolution Multipliers. One of the errors was fixed by commit ea427a222d8b ("HID: core: Fix deadloop in hid_apply_multiplier."), but the other has not been fixed. This error arises because hid_apply_multipler() assumes that every Resolution Multiplier control is contained in a Logical Collection, i.e., there's no way the routine can ever set multiplier_collection to NULL. This is in spite of the fact that the function starts with a big comment saying: * "The Resolution Multiplier control must be contained in the same * Logical Collection as the control(s) to which it is to be applied. ... * If no Logical Collection is * defined, the Resolution Multiplier is associated with all * controls in the report." * HID Usage Table, v1.12, Section 4.3.1, p30 * * Thus, search from the current collection upwards until we find a * logical collection... The comment and the code overlook the possibility that none of the collections found may be a Logical Collection. The fix is to set the multiplier_collection pointer to NULL if the collection found isn't a Logical Collection.

In the Linux kernel, the following vulnerability has been resolved: tomoyo: don't emit warning in tomoyo_write_control() syzbot is reporting too large allocation warning at tomoyo_write_control(), for one can write a very very long line without new line character. To fix this warning, I use __GFP_NOWARN rather than checking for KMALLOC_MAX_SIZE, for practically a valid line should be always shorter than 32KB where the "too small to fail" memory-allocation rule applies. One might try to write a valid line that is longer than 32KB, but such request will likely fail with -ENOMEM. Therefore, I feel that separately returning -EINVAL when a line is longer than KMALLOC_MAX_SIZE is redundant. There is no need to distinguish over-32KB and over-KMALLOC_MAX_SIZE.

In the Linux kernel, the following vulnerability has been resolved: ALSA: memalloc: prefer dma_mapping_error() over explicit address checking With CONFIG_DMA_API_DEBUG enabled, the following warning is observed: DMA-API: snd_hda_intel 0000:03:00.1: device driver failed to check map error[device address=0x00000000ffff0000] [size=20480 bytes] [mapped as single] WARNING: CPU: 28 PID: 2255 at kernel/dma/debug.c:1036 check_unmap+0x1408/0x2430 CPU: 28 UID: 42 PID: 2255 Comm: wireplumber Tainted: G W L 6.12.0-10-133577cad6bf48e5a7848c4338124081393bfe8a+ #759 debug_dma_unmap_page+0xe9/0xf0 snd_dma_wc_free+0x85/0x130 [snd_pcm] snd_pcm_lib_free_pages+0x1e3/0x440 [snd_pcm] snd_pcm_common_ioctl+0x1c9a/0x2960 [snd_pcm] snd_pcm_ioctl+0x6a/0xc0 [snd_pcm] ...

In the Linux kernel, the following vulnerability has been resolved: firmware: qcom: scm: Fix missing read barrier in qcom_scm_get_tzmem_pool() Commit 2e4955167ec5 ("firmware: qcom: scm: Fix __scm and waitq completion variable initialization") introduced a write barrier in probe function to store global '__scm' variable. We all known barriers are paired (see memory-barriers.txt: "Note that write barriers should normally be paired with read or address-dependency barriers"), therefore accessing it from concurrent contexts requires read barrier. Previous commit added such barrier in qcom_scm_is_available(), so let's use that directly. Lack of this read barrier can result in fetching stale '__scm' variable value, NULL, and dereferencing it. Note that barrier in qcom_scm_is_available() satisfies here the control dependency.

In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: fix memory leaks and invalid access at probe error path Deinitialize at reverse order when probe fails. When init_sw_vars fails, rtl_deinit_core should not be called, specially now that it destroys the rtl_wq workqueue. And call rtl_pci_deinit and deinit_sw_vars, otherwise, memory will be leaked. Remove pci_set_drvdata call as it will already be cleaned up by the core driver code and could lead to memory leaks too. cf. commit 8d450935ae7f ("wireless: rtlwifi: remove unnecessary pci_set_drvdata()") and commit 3d86b93064c7 ("rtlwifi: Fix PCI probe error path orphaned memory").

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: add srng->lock for ath11k_hal_srng_* in monitor mode ath11k_hal_srng_* should be used with srng->lock to protect srng data. For ath11k_dp_rx_mon_dest_process() and ath11k_dp_full_mon_process_rx(), they use ath11k_hal_srng_* for many times but never call srng->lock. So when running (full) monitor mode, warning will occur: RIP: 0010:ath11k_hal_srng_dst_peek+0x18/0x30 [ath11k] Call Trace: ? ath11k_hal_srng_dst_peek+0x18/0x30 [ath11k] ath11k_dp_rx_process_mon_status+0xc45/0x1190 [ath11k] ? idr_alloc_u32+0x97/0xd0 ath11k_dp_rx_process_mon_rings+0x32a/0x550 [ath11k] ath11k_dp_service_srng+0x289/0x5a0 [ath11k] ath11k_pcic_ext_grp_napi_poll+0x30/0xd0 [ath11k] __napi_poll+0x30/0x1f0 net_rx_action+0x198/0x320 __do_softirq+0xdd/0x319 So add srng->lock for them to avoid such warnings. Inorder to fetch the srng->lock, should change srng's definition from 'void' to 'struct hal_srng'. And initialize them elsewhere to prevent one line of code from being too long. This is consistent with other ring process functions, such as ath11k_dp_process_rx().

In the Linux kernel, the following vulnerability has been resolved: mmc: mmc_spi: fix error handling in mmc_spi_probe() If mmc_add_host() fails, it doesn't need to call mmc_remove_host(), or it will cause null-ptr-deref, because of deleting a not added device in mmc_remove_host(). To fix this, goto label 'fail_glue_init', if mmc_add_host() fails, and change the label 'fail_add_host' to 'fail_gpiod_request'.

In the Linux kernel, the following vulnerability has been resolved: iio: adc: ti-ads1298: Add NULL check in ads1298_init devm_kasprintf() can return a NULL pointer on failure. A check on the return value of such a call in ads1298_init() is missing. Add it.

In the Linux kernel, the following vulnerability has been resolved: phy: rockchip: samsung-hdptx: Set drvdata before enabling runtime PM In some cases, rk_hdptx_phy_runtime_resume() may be invoked before platform_set_drvdata() is executed in ->probe(), leading to a NULL pointer dereference when using the return of dev_get_drvdata(). Ensure platform_set_drvdata() is called before devm_pm_runtime_enable().

In the Linux kernel, the following vulnerability has been resolved: rtc: tps6594: Fix integer overflow on 32bit systems The problem is this multiply in tps6594_rtc_set_offset() tmp = offset * TICKS_PER_HOUR; The "tmp" variable is an s64 but "offset" is a long in the (-277774)-277774 range. On 32bit systems a long can hold numbers up to approximately two billion. The number of TICKS_PER_HOUR is really large, (32768 * 3600) or roughly a hundred million. When you start multiplying by a hundred million it doesn't take long to overflow the two billion mark. Probably the safest way to fix this is to change the type of TICKS_PER_HOUR to long long because it's such a large number.

In the Linux kernel, the following vulnerability has been resolved: netfs: Fix ceph copy to cache on write-begin At the end of netfs_unlock_read_folio() in which folios are marked appropriately for copying to the cache (either with by being marked dirty and having their private data set or by having PG_private_2 set) and then unlocked, the folio_queue struct has the entry pointing to the folio cleared. This presents a problem for netfs_pgpriv2_write_to_the_cache(), which is used to write folios marked with PG_private_2 to the cache as it expects to be able to trawl the folio_queue list thereafter to find the relevant folios, leading to a hang. Fix this by not clearing the folio_queue entry if we're going to do the deprecated copy-to-cache. The clearance will be done instead as the folios are written to the cache. This can be reproduced by starting cachefiles, mounting a ceph filesystem with "-o fsc" and writing to it.

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: check dpu_plane_atomic_print_state() for valid sspp Similar to the r_pipe sspp protect, add a check to protect the pipe state prints to avoid NULL ptr dereference for cases when the state is dumped without a corresponding atomic_check() where the pipe->sspp is assigned.

In the Linux kernel, the following vulnerability has been resolved: crypto: tegra - do not transfer req when tegra init fails The tegra_cmac_init or tegra_sha_init function may return an error when memory is exhausted. It should not transfer the request when they return an error.

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix legacy client tracking initialization Get rid of the nfsd4_legacy_tracking_ops->init() call in check_for_legacy_methods(). That will be handled in the caller (nfsd4_client_tracking_init()). Otherwise, we'll wind up calling nfsd4_legacy_tracking_ops->init() twice, and the second time we'll trigger the BUG_ON() in nfsd4_init_recdir().

In the Linux kernel, the following vulnerability has been resolved: net/sctp: Prevent autoclose integer overflow in sctp_association_init() While by default max_autoclose equals to INT_MAX / HZ, one may set net.sctp.max_autoclose to UINT_MAX. There is code in sctp_association_init() that can consequently trigger overflow.

In the Linux kernel, the following vulnerability has been resolved: tls: stop recv() if initial process_rx_list gave us non-DATA If we have a non-DATA record on the rx_list and another record of the same type still on the queue, we will end up merging them: - process_rx_list copies the non-DATA record - we start the loop and process the first available record since it's of the same type - we break out of the loop since the record was not DATA Just check the record type and jump to the end in case process_rx_list did some work.

In the Linux kernel, the following vulnerability has been resolved: media: uvcvideo: Fix deadlock during uvc_probe If uvc_probe() fails, it can end up calling uvc_status_unregister() before uvc_status_init() is called. Fix this by checking if dev->status is NULL or not in uvc_status_unregister().

In the Linux kernel, the following vulnerability has been resolved: mailbox: th1520: Fix a NULL vs IS_ERR() bug The devm_ioremap() function doesn't return error pointers, it returns NULL. Update the error checking to match.

In the Linux kernel, the following vulnerability has been resolved: ASoC: soc-pcm: don't use soc_pcm_ret() on .prepare callback commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port" log severity") ignores -EINVAL error message on common soc_pcm_ret(). It is used from many functions, ignoring -EINVAL is over-kill. The reason why -EINVAL was ignored was it really should only be used upon invalid parameters coming from userspace and in that case we don't want to log an error since we do not want to give userspace a way to do a denial-of-service attack on the syslog / diskspace. So don't use soc_pcm_ret() on .prepare callback is better idea.

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix divide error in DM plane scale calcs dm_get_plane_scale doesn't take into account plane scaled size equal to zero, leading to a kernel oops due to division by zero. Fix by setting out-scale size as zero when the dst size is zero, similar to what is done by drm_calc_scale(). This issue started with the introduction of cursor ovelay mode that uses this function to assess cursor mode changes via dm_crtc_get_cursor_mode() before checking plane state.

Since the max send sge is reported as 13, the stack can give requests up to 13 SGEs. This is causing traffic failures and system crashes. Use the define for max SGE supported for variable size. This will work for both static and variable WQEs.

In the Linux kernel, the following vulnerability has been resolved: jfs: add check read-only before truncation in jfs_truncate_nolock() Added a check for "read-only" mode in the `jfs_truncate_nolock` function to avoid errors related to writing to a read-only filesystem.

Instead, the `xtTruncate` function will be called with the "COMMIT_WMAP" flag, preventing modifications in "read-only" mode.

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: prohibit deactivating all links In the internal API this calls this is a WARN_ON, but that should remain since internally we want to know about bugs that may cause this. Prevent deactivating all links in the debugfs write directly.

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: tests: Fix potential NULL dereference in test_cfg80211_parse_colocated_ap() kunit_kzalloc() may return NULL, dereferencing it without NULL check may lead to NULL dereference. Add a NULL check for ies.

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: fix NULL deref check in mt7925_change_vif_links In mt7925_change_vif_links() devm_kzalloc() may return NULL but this returned value is not checked.

In the Linux kernel, the following vulnerability has been resolved: usb: xhci: Fix NULL pointer dereference on certain command aborts If a command is queued to the final usable TRB of a ring segment, the enqueue pointer is advanced to the subsequent link TRB and no further. If the command is later aborted, when the abort completion is handled the dequeue pointer is advanced to the first TRB of the next segment. If no further commands are queued, xhci_handle_stopped_cmd_ring() sees the ring pointers unequal and assumes that there is a pending command, so it calls xhci_mod_cmd_timer() which crashes if cur_cmd was NULL. Don't attempt timer setup if cur_cmd is NULL. The subsequent doorbell ring likely is unnecessary too, but it's harmless. Leave it alone. This is probably Bug 219532, but no confirmation has been received. The issue has been independently reproduced and confirmed fixed using a USB MCU programmed to NAK the Status stage of SET_ADDRESS forever. Everything continued working normally after several prevented crashes.

In the Linux kernel, the following vulnerability has been resolved: media: imx-jpeg: Fix potential error pointer dereference in detach_pm() The proble is on the first line: if (jpeg->pd_dev[i] && !pm_runtime_suspended(jpeg->pd_dev[i])) If jpeg->pd_dev[i] is an error pointer, then passing it to pm_runtime_suspended() will lead to an Oops. The other conditions check for both error pointers and NULL, but it would be more clear to use the IS_ERR_OR_NULL() check for that.

In the Linux kernel, the following vulnerability has been resolved: binfmt_flat: Fix integer overflow bug on 32 bit systems Most of these sizes and counts are capped at 256MB so the math doesn't result in an integer overflow. The "relocs" count needs to be checked as well. Otherwise on 32bit systems the calculation of "full_data" could be wrong. full_data = data_len + relocs * sizeof(unsigned long);

In the Linux kernel, the following vulnerability has been resolved: PCI: imx6: Fix suspend/resume support on i.MX6QDL The suspend/resume functionality is currently broken on the i.MX6QDL platform, as documented in the NXP errata (ERR005723): https://www.nxp.com/docs/en/errata/IMX6DQCE.pdf This patch addresses the issue by sharing most of the suspend/resume sequences used by other i.MX devices, while avoiding modifications to critical registers that disrupt the PCIe functionality. It targets the same problem as the following downstream commit: https://github.com/nxp-imx/linux-imx/commit/4e92355e1f79d225ea842511fcfd42b343b32995 Unlike the downstream commit, this patch also resets the connected PCIe device if possible. Without this reset, certain drivers, such as ath10k or iwlwifi, will crash on resume. The device reset is also done by the driver on other i.MX platforms, making this patch consistent with existing practices. Upon resuming, the kernel will hang and display an error. Here's an example of the error encountered with the ath10k driver: ath10k_pci 0000:01:00.0: Unable to change power state from D3hot to D0, device inaccessible Unhandled fault: imprecise external abort (0x1406) at 0x0106f944 Without this patch, suspend/resume will fail on i.MX6QDL devices if a PCIe device is connected.

In the Linux kernel, the following vulnerability has been resolved: PCI: dwc: ep: Prevent changing BAR size/flags in pci_epc_set_bar() In commit 4284c88fff0e ("PCI: designware-ep: Allow pci_epc_set_bar() update inbound map address") set_bar() was modified to support dynamically changing the backing physical address of a BAR that was already configured. This means that set_bar() can be called twice, without ever calling clear_bar() (as calling clear_bar() would clear the BAR's PCI address assigned by the host). This can only be done if the new BAR size/flags does not differ from the existing BAR configuration. Add these missing checks. If we allow set_bar() to set e.g. a new BAR size that differs from the existing BAR size, the new address translation range will be smaller than the BAR size already determined by the host, which would mean that a read past the new BAR size would pass the iATU untranslated, which could allow the host to read memory not belonging to the new struct pci_epf_bar. While at it, add comments which clarifies the support for dynamically changing the physical address of a BAR. (Which was also missing.)

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btbcm: Fix NULL deref in btbcm_get_board_name() devm_kstrdup() can return a NULL pointer on failure,but this returned value in btbcm_get_board_name() is not checked. Add NULL check in btbcm_get_board_name(), to handle kernel NULL pointer dereference error.

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix deadlock when freeing cgroup storage The following commit bc235cdb423a ("bpf: Prevent deadlock from recursive bpf_task_storage_[get|delete]") first introduced deadlock prevention for fentry/fexit programs attaching on bpf_task_storage helpers. That commit also employed the logic in map free path in its v6 version. Later bpf_cgrp_storage was first introduced in c4bcfb38a95e ("bpf: Implement cgroup storage available to non-cgroup-attached bpf progs") which faces the same issue as bpf_task_storage, instead of its busy counter, NULL was passed to bpf_local_storage_map_free() which opened a window to cause deadlock: <TASK> (acquiring local_storage->lock) _raw_spin_lock_irqsave+0x3d/0x50 bpf_local_storage_update+0xd1/0x460 bpf_cgrp_storage_get+0x109/0x130 bpf_prog_a4d4a370ba857314_cgrp_ptr+0x139/0x170 ? __bpf_prog_enter_recur+0x16/0x80 bpf_trampoline_6442485186+0x43/0xa4 cgroup_storage_ptr+0x9/0x20 (holding local_storage->lock) bpf_selem_unlink_storage_nolock.constprop.0+0x135/0x160 bpf_selem_unlink_storage+0x6f/0x110 bpf_local_storage_map_free+0xa2/0x110 bpf_map_free_deferred+0x5b/0x90 process_one_work+0x17c/0x390 worker_thread+0x251/0x360 kthread+0xd2/0x100 ret_from_fork+0x34/0x50 ret_from_fork_asm+0x1a/0x30 </TASK> Progs: - A: SEC("fentry/cgroup_storage_ptr") - cgid (BPF_MAP_TYPE_HASH) Record the id of the cgroup the current task belonging to in this hash map, using the address of the cgroup as the map key. - cgrpa (BPF_MAP_TYPE_CGRP_STORAGE) If current task is a kworker, lookup the above hash map using function parameter @owner as the key to get its corresponding cgroup id which is then used to get a trusted pointer to the cgroup through bpf_cgroup_from_id(). This trusted pointer can then be passed to bpf_cgrp_storage_get() to finally trigger the deadlock issue. - B: SEC("tp_btf/sys_enter") - cgrpb (BPF_MAP_TYPE_CGRP_STORAGE) The only purpose of this prog is to fill Prog A's hash map by calling bpf_cgrp_storage_get() for as many userspace tasks as possible. Steps to reproduce: - Run A; - while (true) { Run B; Destroy B; } Fix this issue by passing its busy counter to the free procedure so it can be properly incremented before storage/smap locking.

Rename helpers to better reflect they are safe against BH only. - ptr_ring_resize_multiple() to ptr_ring_resize_multiple_bh() - skb_array_resize_multiple() to skb_array_resize_multiple_bh() [1] WARNING: CPU: 1 PID: 9150 at net/core/page_pool.c:709 __page_pool_put_page net/core/page_pool.c:709 [inline] WARNING: CPU: 1 PID: 9150 at net/core/page_pool.c:709 page_pool_put_unrefed_netmem+0x157/0xa40 net/core/page_pool.c:780 Modules linked in: CPU: 1 UID: 0 PID: 9150 Comm: syz.1.1052 Not tainted 6.11.0-rc3-syzkaller-00202-gf8669d7b5f5d #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 08/06/2024 RIP: 0010:__page_pool_put_page net/core/page_pool.c:709 [inline] RIP: 0010:page_pool_put_unrefed_netmem+0x157/0xa40 net/core/page_pool.c:780 Code: 74 0e e8 7c aa fb f7 eb 43 e8 75 aa fb f7 eb 3c 65 8b 1d 38 a8 6a 76 31 ff 89 de e8 a3 ae fb f7 85 db 74 0b e8 5a aa fb f7 90 <0f> 0b 90 eb 1d 65 8b 1d 15 a8 6a 76 31 ff 89 de e8 84 ae fb f7 85 RSP: 0018:ffffc9000bda6b58 EFLAGS: 00010083 RAX: ffffffff8997e523 RBX: 0000000000000000 RCX: 0000000000040000 RDX: ffffc9000fbd0000 RSI: 0000000000001842 RDI: 0000000000001843 RBP: 0000000000000000 R08: ffffffff8997df2c R09: 1ffffd40003a000d R10: dffffc0000000000 R11: fffff940003a000e R12: ffffea0001d00040 R13: ffff88802e8a4000 R14: dffffc0000000000 R15: 00000000ffffffff FS: 00007fb7aaf716c0(0000) GS:ffff8880b9300000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fa15a0d4b72 CR3: 00000000561b0000 CR4: 00000000003506f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: <TASK> tun_ptr_free drivers/net/tun.c:617 [inline] __ptr_ring_swap_queue include/linux/ptr_ring.h:571 [inline] ptr_ring_resize_multiple_noprof include/linux/ptr_ring.h:643 [inline] tun_queue_resize drivers/net/tun.c:3694 [inline] tun_device_event+0xaaf/0x1080 drivers/net/tun.c:3714 notifier_call_chain+0x19f/0x3e0 kernel/notifier.c:93 call_netdevice_notifiers_extack net/core/dev.c:2032 [inline] call_netdevice_notifiers net/core/dev.c:2046 [inline] dev_change_tx_queue_len+0x158/0x2a0 net/core/dev.c:9024 do_setlink+0xff6/0x41f0 net/core/rtnetlink.c:2923 rtnl_setlink+0x40d/0x5a0 net/core/rtnetlink.c:3201 rtnetlink_rcv_msg+0x73f/0xcf0 net/core/rtnetlink.c:6647 netlink_rcv_skb+0x1e3/0x430 net/netlink/af_netlink.c:2550

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix RCU stall while reaping monitor destination ring While processing the monitor destination ring, MSDUs are reaped from the link descriptor based on the corresponding buf_id. However, sometimes the driver cannot obtain a valid buffer corresponding to the buf_id received from the hardware. This causes an infinite loop in the destination processing, resulting in a kernel crash. kernel log: ath11k_pci 0000:58:00.0: data msdu_pop: invalid buf_id 309 ath11k_pci 0000:58:00.0: data dp_rx_monitor_link_desc_return failed ath11k_pci 0000:58:00.0: data msdu_pop: invalid buf_id 309 ath11k_pci 0000:58:00.0: data dp_rx_monitor_link_desc_return failed Fix this by skipping the problematic buf_id and reaping the next entry, replacing the break with the next MSDU processing.

In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: pltfrm: Dellocate HBA during ufshcd_pltfrm_remove() This will ensure that the scsi host is cleaned up properly using scsi_host_dev_release(). Otherwise, it may lead to memory leaks.

In the Linux kernel, the following vulnerability has been resolved: riscv: Fix sleeping in invalid context in die() die() can be called in exception handler, and therefore cannot sleep. However, die() takes spinlock_t which can sleep with PREEMPT_RT enabled. That causes the following warning: BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48 in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 285, name: mutex preempt_count: 110001, expected: 0 RCU nest depth: 0, expected: 0 CPU: 0 UID: 0 PID: 285 Comm: mutex Not tainted 6.12.0-rc7-00022-ge19049cf7d56-dirty #234 Hardware name: riscv-virtio,qemu (DT) Call Trace: dump_backtrace+0x1c/0x24 show_stack+0x2c/0x38 dump_stack_lvl+0x5a/0x72 dump_stack+0x14/0x1c __might_resched+0x130/0x13a rt_spin_lock+0x2a/0x5c die+0x24/0x112 do_trap_insn_illegal+0xa0/0xea _new_vmalloc_restore_context_a0+0xcc/0xd8 Oops - illegal instruction [#1] Switch to use raw_spinlock_t, which does not sleep even with PREEMPT_RT enabled.
