Linux Kernel AMD GPU Memory Leak Vulnerability in MES Self-Test

A memory leak vulnerability has been identified in the Linux kernel's AMD GPU driver, specifically within the Memory Engine Scheduler (MES) self-test. The issue arises because the fences associated with the MES queue are not properly freed during the cleanup process, leading to a memory leak. This vulnerability affects the Linux kernel stable tree.

Impact

Exploitation of this vulnerability leads to a memory leak, which can cause increased memory usage and potentially degrade system performance over time.

Reproduction

The vulnerability can be reproduced by running the AMD GPU driver with the MES self-test enabled. During the test, the fences associated with the MES queue are not freed properly, causing a memory leak.

Remediation

Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
