In the Linux kernel, the following vulnerability has been resolved: mm/damon/sysfs-schemes: free old damon_sysfs_scheme_filter->memcg_path on write memcg_path_store() assigns a newly allocated memory buffer to filter->memcg_path, without deallocating the previously allocated and assigned memory buffer. As a result, users can leak kernel memory by continuously writing a data to memcg_path DAMOS sysfs file. Fix the leak by deallocating the previously set memory buffer.
The fUSBHub driver in the PCoIP Software Client prior to version 21.07.0 had an error in object management during the handling of a variety of IOCTLs, which allowed an attacker to cause a denial of service.

In the Linux kernel, the following vulnerability has been resolved: fs/binfmt_elf: Fix memory leak in load_elf_binary() There is a memory leak reported by kmemleak: unreferenced object 0xffff88817104ef80 (size 224): comm "xfs_admin", pid 47165, jiffies 4298708825 (age 1333.476s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 60 a8 b3 00 81 88 ff ff a8 10 5a 00 81 88 ff ff `.........Z..... backtrace: [<ffffffff819171e1>] __alloc_file+0x21/0x250 [<ffffffff81918061>] alloc_empty_file+0x41/0xf0 [<ffffffff81948cda>] path_openat+0xea/0x3d30 [<ffffffff8194ec89>] do_filp_open+0x1b9/0x290 [<ffffffff8192660e>] do_open_execat+0xce/0x5b0 [<ffffffff81926b17>] open_exec+0x27/0x50 [<ffffffff81a69250>] load_elf_binary+0x510/0x3ed0 [<ffffffff81927759>] bprm_execve+0x599/0x1240 [<ffffffff8192a997>] do_execveat_common.isra.0+0x4c7/0x680 [<ffffffff8192b078>] __x64_sys_execve+0x88/0xb0 [<ffffffff83bbf0a5>] do_syscall_64+0x35/0x80 If "interp_elf_ex" fails to allocate memory in load_elf_binary(), the program will take the "out_free_ph" error handing path, resulting in "interpreter" file resource is not released. Fix it by adding an error handing path "out_free_file", which will release the file resource when "interp_elf_ex" failed to allocate memory.
In the Linux kernel, the following vulnerability has been resolved: media: pvrusb2: fix memory leak in pvr_probe The error handling code in pvr2_hdw_create forgets to unregister the v4l2 device. When pvr2_hdw_create returns back to pvr2_context_create, it calls pvr2_context_destroy to destroy context, but mp->hdw is NULL, which leads to that pvr2_hdw_destroy directly returns. Fix this by adding v4l2_device_unregister to decrease the refcount of usb interface.
In the Linux kernel, the following vulnerability has been resolved: net: usb: rtl8150: fix memory leak on usb_submit_urb() failure In async_set_registers(), when usb_submit_urb() fails, the allocated async_req structure and URB are not freed, causing a memory leak. The completion callback async_set_reg_cb() is responsible for freeing these allocations, but it is only called after the URB is successfully submitted and completes (successfully or with error). If submission fails, the callback never runs and the memory is leaked. Fix this by freeing both the URB and the request structure in the error path when usb_submit_urb() fails.
In the Linux kernel, the following vulnerability has been resolved: memory: mtk-smi: fix device leak on larb probe Make sure to drop the reference taken when looking up the SMI device during larb probe on late probe failure (e.g. probe deferral) and on driver unbind.
In the Linux kernel, the following vulnerability has been resolved: ksmbd: Fix memory leak in get_file_all_info() In get_file_all_info(), if vfs_getattr() fails, the function returns immediately without freeing the allocated filename, leading to a memory leak. Fix this by freeing the filename before returning in this error case.
In the Linux kernel, the following vulnerability has been resolved: KEYS: trusted: Fix a memory leak in tpm2_load_cmd 'tpm2_load_cmd' allocates a tempoary blob indirectly via 'tpm2_key_decode' but it is not freed in the failure paths. Address this by wrapping the blob into with a cleanup helper.
In the Linux kernel, the following vulnerability has been resolved: powerpc/52xx: Fix a resource leak in an error handling path The error handling path of mpc52xx_lpbfifo_probe() has a request_irq() that is not balanced by a corresponding free_irq(). Add the missing call, as already done in the remove function.
In the Linux kernel, the following vulnerability has been resolved: drm/amd: fix potential memory leak This patch fix potential memory leak (clk_src) when function run into last return NULL. s/free/kfree/ - Alex
In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: fix device leaks on compat bind and unbind Make sure to drop the reference taken when looking up the idxd device as part of the compat bind and unbind sysfs interface.
In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw: dmamux: fix OF node leak on route allocation failure Make sure to drop the reference taken to the DMA master OF node also on late route allocation failures.
In the Linux kernel, the following vulnerability has been resolved: dmaengine: stm32: dmamux: fix device leak on route allocation Make sure to drop the reference taken when looking up the DMA mux platform device during route allocation. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference.
In the Linux kernel, the following vulnerability has been resolved: misc: ti_fpc202: fix a potential memory leak in probe function Use for_each_child_of_node_scoped() to simplify the code and ensure the device node reference is automatically released when the loop scope ends.
In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: k3-udma-glue: fix memory leak when register device fail If device_register() fails, it should call put_device() to give up reference, the name allocated in dev_set_name() can be freed in callback function kobject_cleanup().
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: fix ntfs_mount_options leak in ntfs_fill_super() In ntfs_fill_super(), the fc->fs_private pointer is set to NULL without first freeing the memory it points to. This causes the subsequent call to ntfs_fs_free() to skip freeing the ntfs_mount_options structure. This results in a kmemleak report: unreferenced object 0xff1100015378b800 (size 32): comm "mount", pid 582, jiffies 4294890685 hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 ed ff ed ff 00 04 00 00 ................ backtrace (crc ed541d8c): __kmalloc_cache_noprof+0x424/0x5a0 __ntfs_init_fs_context+0x47/0x590 alloc_fs_context+0x5d8/0x960 __x64_sys_fsopen+0xb1/0x190 do_syscall_64+0x50/0x1f0 entry_SYSCALL_64_after_hwframe+0x76/0x7e This issue can be reproduced using the following commands: fallocate -l 100M test.file mount test.file /tmp/test Since sbi->options is duplicated from fc->fs_private and does not directly use the memory allocated for fs_private, it is unnecessary to set fc->fs_private to NULL. Additionally, this patch simplifies the code by utilizing the helper function put_mount_options() instead of open-coding the cleanup logic.
In the Linux kernel, the following vulnerability has been resolved: ntb_netdev: Use dev_kfree_skb_any() in interrupt context TX/RX callback handlers (ntb_netdev_tx_handler(), ntb_netdev_rx_handler()) can be called in interrupt context via the DMA framework when the respective DMA operations have completed. As such, any calls by these routines to free skb's, should use the interrupt context safe dev_kfree_skb_any() function. Previously, these callback handlers would call the interrupt unsafe version of dev_kfree_skb(). This has not presented an issue on Intel IOAT DMA engines as that driver utilizes tasklets rather than a hard interrupt handler, like the AMD PTDMA DMA driver. On AMD systems, a kernel WARNING message is encountered, which is being issued from skb_release_head_state() due to in_hardirq() being true. Besides the user visible WARNING from the kernel, the other symptom of this bug was that TCP/IP performance across the ntb_netdev interface was very poor, i.e. approximately an order of magnitude below what was expected. With the repair to use dev_kfree_skb_any(), kernel WARNINGs from skb_release_head_state() ceased and TCP/IP performance, as measured by iperf, was on par with expected results, approximately 20 Gb/s on AMD Milan based server. Note that this performance is comparable with Intel based servers.
In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: Use devm_kmemdup() in rtw_set_supported_band() Simplify the code by using device managed memory allocations. This also fixes a memory leak in rtw_register_hw(). The supported bands were not freed in the error path. Copied from commit 145df52a8671 ("wifi: rtw89: Convert rtw89_core_set_supported_band to use devm_*").
In the Linux kernel, the following vulnerability has been resolved: dmaengine: lpc18xx-dmamux: fix device leak on route allocation Make sure to drop the reference taken when looking up the DMA mux platform device during route allocation. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference.
In the Linux kernel, the following vulnerability has been resolved: memory: mtk-smi: fix device leaks on common probe Make sure to drop the reference taken when looking up the SMI device during common probe on late probe failure (e.g. probe deferral) and on driver unbind.
In the Linux kernel, the following vulnerability has been resolved: apparmor: Fix memleak in aa_simple_write_to_buffer() When copy_from_user failed, the memory is freed by kvfree. however the management struct and data blob are allocated independently, so only kvfree(data) cause a memleak issue here. Use aa_put_loaddata(data) to fix this issue.
In the Linux kernel, the following vulnerability has been resolved: dmaengine: sh: rz-dmac: fix device leak on probe failure Make sure to drop the reference taken when looking up the ICU device during probe also on probe failures (e.g. probe deferral).
A vulnerability, which was classified as problematic, has been found in HDF5 1.14.6. This issue affects the function H5FL__malloc of the file src/H5FL.c. The manipulation leads to memory leak. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used.
In the Linux kernel, the following vulnerability has been resolved: ASoC: stm32: sai: fix OF node leak on probe The reference taken to the sync provider OF node when probing the platform device is currently only dropped if the set_sync() callback fails during DAI probe. Make sure to drop the reference on platform probe failures (e.g. probe deferral) and on driver unbind. This also avoids a potential use-after-free in case the DAI is ever reprobed without first rebinding the platform driver.
In the Linux kernel, the following vulnerability has been resolved: mmc: vub300: fix return value check of mmc_add_host() mmc_add_host() may return error, if we ignore its return value, the memory that allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added device in the remove path. So fix this by checking the return value and goto error path which will call mmc_free_host(), besides, the timer added before mmc_add_host() needs be del. And this patch fixes another missing call mmc_free_host() if usb_control_msg() fails.
In the Linux kernel, the following vulnerability has been resolved: most: core: fix resource leak in most_register_interface error paths The function most_register_interface() did not correctly release resources if it failed early (before registering the device). In these cases, it returned an error code immediately, leaking the memory allocated for the interface. Fix this by initializing the device early via device_initialize() and calling put_device() on all error paths. The most_register_interface() is expected to call put_device() on error which frees the resources allocated in the caller. The put_device() either calls release_mdev() or dim2_release(), depending on the caller. Switch to using device_add() instead of device_register() to handle the split initialization.
In the Linux kernel, the following vulnerability has been resolved: via_wdt: fix critical boot hang due to unnamed resource allocation The VIA watchdog driver uses allocate_resource() to reserve a MMIO region for the watchdog control register. However, the allocated resource was not given a name, which causes the kernel resource tree to contain an entry marked as "<BAD>" under /proc/iomem on x86 platforms. During boot, this unnamed resource can lead to a critical hang because subsequent resource lookups and conflict checks fail to handle the invalid entry properly.
