| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
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.
