The NVMe driver function nvme_opc_get_log_page is vulnerable to a buffer over-read from a guest-controlled value.
The virtio_vq_recordon function is subject to a time-of-check to time-of-use (TOCTOU) race condition.
The NVMe driver queue processing is vulernable to guest-induced infinite loops.
In FreeBSD 12.0-STABLE before r350246, 12.0-RELEASE before 12.0-RELEASE-p8, 11.3-STABLE before r350247, 11.3-RELEASE before 11.3-RELEASE-p1, and 11.2-RELEASE before 11.2-RELEASE-p12, the emulated XHCI device included with the bhyve hypervisor did not properly validate data provided by the guest, allowing an out-of-bounds read. This provides a malicious guest the possibility to crash the system or access system memory.
In FreeBSD 12.0-STABLE before r350648, 12.0-RELEASE before 12.0-RELEASE-p9, 11.3-STABLE before r350650, 11.3-RELEASE before 11.3-RELEASE-p2, and 11.2-RELEASE before 11.2-RELEASE-p13, the ICMPv6 input path incorrectly handles cases where an MLDv2 listener query packet is internally fragmented across multiple mbufs. A remote attacker may be able to cause an out-of-bounds read or write that may cause the kernel to attempt to access an unmapped page and subsequently panic.
The ctl_request_sense function could expose up to three bytes of the kernel heap to userspace. Malicious software running in a guest VM that exposes virtio_scsi can exploit the vulnerabilities to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process. A malicious iSCSI initiator could achieve remote code execution on the iSCSI target host.
The MATCH_ASSOC function in NTP before version 4.2.8p9 and 4.3.x before 4.3.92 allows remote attackers to cause an out-of-bounds reference via an addpeer request with a large hmode value.
Malicious software running in a guest VM can exploit the buffer overflow to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process.
An insufficient boundary validation in the USB code could lead to an out-of-bounds read on the heap, which could potentially lead to an arbitrary write and remote code execution.
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
Local user gains root privileges via buffer overflow in rdist, via expstr() function.
When dumping core and saving process information, proc_getargv() might return an sbuf which have a sbuf_len() of 0 or -1, which is not properly handled. An out-of-bound read can happen when user constructs a specially crafted ps_string, which in turn can cause the kernel to crash.
In FreeBSD through 11.1, the smb_strdupin function in sys/netsmb/smb_subr.c has a race condition with a resultant out-of-bounds read, because it can cause t2p->t_name strings to lack a final '\0' character.
libfetch before 2021-07-26, as used in apk-tools, xbps, and other products, mishandles numeric strings for the FTP and HTTP protocols. The FTP passive mode implementation allows an out-of-bounds read because strtol is used to parse the relevant numbers into address bytes. It does not check if the line ends prematurely. If it does, the for-loop condition checks for the '\0' terminator one byte too late.
In FreeBSD 12.0-STABLE before r350637, 12.0-RELEASE before 12.0-RELEASE-p9, 11.3-STABLE before r350638, 11.3-RELEASE before 11.3-RELEASE-p2, and 11.2-RELEASE before 11.2-RELEASE-p13, the bsnmp library is not properly validating the submitted length from a type-length-value encoding. A remote user could cause an out-of-bounds read or trigger a crash of the software such as bsnmpd resulting in a denial of service.
Out-of-bounds Read vulnerability in Open Networking Foundation (ONF) libfluid (libfluid_msg module). This vulnerability is associated with program routine fluid_msg::of10::StatsReplyPort::unpack. This issue affects libfluid: 0.1.0.

A memory disclosure vulnerability exists in libcoap's OSCORE configuration parser in libcoap before release-4.3.5-patches. An out-of-bounds read may occur when parsing certain configuration values, allowing an attacker to infer or read memory beyond string boundaries in the .rodata section. This could potentially lead to information disclosure or denial of service.
Out-of-bounds Read vulnerability in Open Networking Foundation (ONF) libfluid (libfluid_msg module). This vulnerability is associated with program routine fluid_msg::of10::StatsReplyFlow::unpack. This issue affects libfluid: 0.1.0.
ESP-NOW Component provides a connectionless Wi-Fi communication protocol. An Out-of-Bound (OOB) vulnerability was discovered in the implementation of the ESP-NOW group type message because there is no check for the addrs_num field of the group type message. This can result in memory corruption related attacks. Normally there are two fields in the group information that need to be checked, i.e., the addrs_num field and the addrs_list fileld. Since we only checked the addrs_list field, an attacker can send a group type message with an invalid addrs_num field, which will cause the message handled by the firmware to be much larger than the current buffer, thus causing a memory corruption issue that goes beyond the payload length.
Out-of-bounds Read vulnerability in Open Networking Foundation (ONF) libfluid (libfluid_msg module). This vulnerability is associated with program routine fluid_msg::of13::MultipartReplyMeterConfig::unpack. This issue affects libfluid: 0.1.0.

In PHP versions prior to 7.4.33, 8.0.25 and 8.1.12, when using imageloadfont() function in gd extension, it is possible to supply a specially crafted font file, such as if the loaded font is used with imagechar() function, the read outside allocated buffer will be used. This can lead to crashes or disclosure of confidential information.
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btrtl: fix out of bounds memory access The problem is detected by KASAN. btrtl driver uses private hci data to store 'struct btrealtek_data'. If btrtl driver is used with btusb, then memory for private hci data is allocated in btusb. But no private data is allocated after hci_dev, when btrtl is used with hci_h5. This commit adds memory allocation for hci_h5 case. ================================================================== BUG: KASAN: slab-out-of-bounds in btrtl_initialize+0x6cc/0x958 [btrtl] Write of size 8 at addr ffff00000f5a5748 by task kworker/u9:0/76 Hardware name: Pine64 PinePhone (1.2) (DT) Workqueue: hci0 hci_power_on [bluetooth] Call trace: dump_backtrace+0x9c/0x128 show_stack+0x20/0x38 dump_stack_lvl+0x48/0x60 print_report+0xf8/0x5d8 kasan_report+0x90/0xd0 __asan_store8+0x9c/0xc0 [btrtl] h5_btrtl_setup+0xd0/0x2f8 [hci_uart] h5_setup+0x50/0x80 [hci_uart] hci_uart_setup+0xd4/0x260 [hci_uart] hci_dev_open_sync+0x1cc/0xf68 [bluetooth] hci_dev_do_open+0x34/0x90 [bluetooth] hci_power_on+0xc4/0x3c8 [bluetooth] process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 Allocated by task 53: kasan_save_stack+0x3c/0x68 kasan_save_track+0x20/0x40 kasan_save_alloc_info+0x68/0x78 __kasan_kmalloc+0xd4/0xd8 __kmalloc+0x1b4/0x3b0 hci_alloc_dev_priv+0x28/0xa58 [bluetooth] hci_uart_register_device+0x118/0x4f8 [hci_uart] h5_serdev_probe+0xf4/0x178 [hci_uart] serdev_drv_probe+0x54/0xa0 really_probe+0x254/0x588 __driver_probe_device+0xc4/0x210 driver_probe_device+0x64/0x160 __driver_attach_async_helper+0x88/0x158 async_run_entry_fn+0xd0/0x388 process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 Last potentially related work creation: kasan_save_stack+0x3c/0x68 __kasan_record_aux_stack+0xb0/0x150 kasan_record_aux_stack_noalloc+0x14/0x20 __queue_work+0x33c/0x960 queue_work_on+0x98/0xc0 hci_recv_frame+0xc8/0x1e8 [bluetooth] h5_complete_rx_pkt+0x2c8/0x800 [hci_uart] h5_rx_payload+0x98/0xb8 [hci_uart] h5_recv+0x158/0x3d8 [hci_uart] hci_uart_receive_buf+0xa0/0xe8 [hci_uart] ttyport_receive_buf+0xac/0x178 flush_to_ldisc+0x130/0x2c8 process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 Second to last potentially related work creation: kasan_save_stack+0x3c/0x68 __kasan_record_aux_stack+0xb0/0x150 kasan_record_aux_stack_noalloc+0x14/0x20 __queue_work+0x788/0x960 queue_work_on+0x98/0xc0 __hci_cmd_sync_sk+0x23c/0x7a0 [bluetooth] __hci_cmd_sync+0x24/0x38 [bluetooth] btrtl_initialize+0x760/0x958 [btrtl] h5_btrtl_setup+0xd0/0x2f8 [hci_uart] h5_setup+0x50/0x80 [hci_uart] hci_uart_setup+0xd4/0x260 [hci_uart] hci_dev_open_sync+0x1cc/0xf68 [bluetooth] hci_dev_do_open+0x34/0x90 [bluetooth] hci_power_on+0xc4/0x3c8 [bluetooth] process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 ==================================================================
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An out-of-bounds read was found in Exiv2 version v0.28.2. The vulnerability is in the parser for the ASF video format, which was a new feature in v0.28.0. The out-of-bounds read is triggered when Exiv2 is used to read the metadata of a crafted video file. The bug is fixed in version v0.28.3.
AstrBot Project v3.5.22 has an arbitrary file read vulnerability in function _encode_image_bs64. Since the _encode_image_bs64 function defined in entities.py opens the image specified by the user in the request body and returns the image content as a base64-encoded string without checking the legitimacy of the image path, attackers can construct a series of malicious URLs to read any specified file, resulting in sensitive data leakage.
In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _nx_ipv4_packet_receive() function when received an Ethernet frame with less than 4 bytes of IP packet.
In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in _nx_ip_packet_receive() function when received an Ethernet with type set as IP but no IP data.
stb_image is a single file MIT licensed library for processing images. When `stbi_set_flip_vertically_on_load` is set to `TRUE` and `req_comp` is set to a number that doesn’t match the real number of components per pixel, the library attempts to flip the image vertically. A crafted image file can trigger `memcpy` out-of-bounds read because `bytes_per_pixel` used to calculate `bytes_per_row` doesn’t match the real image array dimensions.
stb_image is a single file MIT licensed library for processing images. A crafted image file may trigger out of bounds memcpy read in `stbi__gif_load_next`. This happens because two_back points to a memory address lower than the start of the buffer out. This issue may be used to leak internal memory allocation information.
