CVE-2023-53764

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.1.0-rc2+ #3

Description The Linux kernel contains a flaw within the ath12k driver related to lock handling during peer ID retrieval. Specifically, the ath12k peer find by id() function requires a lock, but this lock is not consistently held in the WBM error path, leading to a potential lockdep assertion failure. This issue occurs when processing errors in the QCN9274 hardware. The ath12k dp rx process wbm err() function calls ath12k peer find by id() without holding the necessary lock.

Recommendations Update to a version of the Linux kernel that addresses this issue.
