CVE-2023-53538

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.12.0-0 fbk13 clang 7455 gb24de3bdb045

Description The Linux kernel contains a flaw within the btrfs subsystem related to tree mod log handling. Specifically, a race condition exists during tree mod log rewind, potentially leading to a kernel panic. This issue arises when logical inode resolution utilizes a tree mod log sequence number and encounters a rewind operation on a busy node. The sequence of tree mod log operations can cause an out-of-bounds write during a memmove operation, resulting in the kernel panic.

Recommendations Update the Linux kernel to version 5.12.0-0 fbk13 clang 7455 gb24de3bdb045 or a later version to address this issue.
