CVE-2023-52632

Name of the Vulnerable Software and Affected Versions Linux kernel versions 6.5.0-kfd-yangp #2289 and earlier

Description A possible circular locking dependency has been detected in the Linux kernel, specifically in the drm/amdkfd module. This issue occurs when a task attempts to acquire a lock that already depends on another lock held by the task. The existing dependency chain involves several functions, including synchronize srcu, mutex lock, and flush work. A possible unsafe locking scenario has been identified, which could lead to a deadlock. The vulnerability affects the Linux kernel's ability to manage locks properly, potentially causing system crashes or freezes.

Recommendations To resolve this issue, update the Linux kernel to a version that includes the fix for the lock dependency warning with srcu. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
