In the Linux kernel, the following vulnerability has been resolved: security/keys: fix slab-out-of-bounds in key_task_permission KASAN reports an out of bounds read: BUG: KASAN: slab-out-of-bounds in __kuid_val include/linux/uidgid.h:36 BUG: KASAN: slab-out-of-bounds in uid_eq include/linux/uidgid.h:63 [inline] BUG: KASAN: slab-out-of-bounds in key_task_permission+0x394/0x410 security/keys/permission.c:54 Read of size 4 at addr ffff88813c3ab618 by task stress-ng/4362 CPU: 2 PID: 4362 Comm: stress-ng Not tainted 5.10.0-14930-gafbffd6c3ede #15 Call Trace: __dump_stack lib/dump_stack.c:82 [inline] dump_stack+0x107/0x167 lib/dump_stack.c:123 print_address_description.constprop.0+0x19/0x170 mm/kasan/report.c:400 __kasan_report.cold+0x6c/0x84 mm/kasan/report.c:560 kasan_report+0x3a/0x50 mm/kasan/report.c:585 __kuid_val include/linux/uidgid.h:36 [inline] uid_eq include/linux/uidgid.h:63 [inline] key_task_permission+0x394/0x410 security/keys/permission.c:54 search_nested_keyrings+0x90e/0xe90 security/keys/keyring.c:793 This issue was also reported by syzbot. It can be reproduced by following these steps(more details [1]): 1. Obtain more than 32 inputs that have similar hashes, which ends with the pattern '0xxxxxxxe6'. 2. Reboot and add the keys obtained in step 1. The reproducer demonstrates how this issue happened: 1. In the search_nested_keyrings function, when it iterates through the slots in a node(below tag ascend_to_node), if the slot pointer is meta and node->back_pointer != NULL(it means a root), it will proceed to descend_to_node. • https://git.kernel.org/stable/c/b2a4df200d570b2c33a57e1ebfa5896e4bc81b69 https://git.kernel.org/stable/c/c3ce634ad953ce48c75c39bdfd8b711dd95f346f https://git.kernel.org/stable/c/4efb69a0e294ef201bcdf7ce3d6202cd0a545a5d https://git.kernel.org/stable/c/1e4332581cd4eed75aea77af6f66cdcdda8b49b9 https://git.kernel.org/stable/c/199c20fb7499c79557a075dc24e9a7dae7d9f1ce https://git.kernel.org/stable/c/bbad2d5b6c99db468d8f88b6ba6a56ed409b4881 https://git.kernel.org/stable/c/3e79ad156bedf2da0ab909a118d2cec6c9c22b79 https://git.kernel.org/stable/c/e0a317ad68e4ea48a0158187238c5407e •

https://notcve.org/view.php?id=CVE-2024-50287
In the Linux kernel, the following vulnerability has been resolved: media: v4l2-tpg: prevent the risk of a division by zero As reported by Coverity, the logic at tpg_precalculate_line() blindly rescales the buffer even when scaled_witdh is equal to zero. If this ever happens, this will cause a division by zero. Instead, add a WARN_ON_ONCE() to trigger such cases and return without doing any precalculation. • https://git.kernel.org/stable/c/63881df94d3ecbb0deafa0b77da62ff2f32961c4 https://git.kernel.org/stable/c/e3c36d0bde309f690ed1f9cd5f7e63b3a513f94a https://git.kernel.org/stable/c/0bfc6e38ee2250f0503d96f1a1de441c31d88715 https://git.kernel.org/stable/c/054931ca3cfcb8e8fa036e887d6f379942b02565 https://git.kernel.org/stable/c/a749c15dccc58d9cbad9cd23bd8ab4b5fa96cf47 https://git.kernel.org/stable/c/c63c30c9d9f2c8de34b16cd2b8400240533b914e https://git.kernel.org/stable/c/2d0f01aa602fd15a805771bdf3f4d9a9b4df7f47 https://git.kernel.org/stable/c/0cdb42ba0b28f548c1a4e86bb8489dba0 •
