AI-suggested
A fix for this vulnerability is available and should be applied by updating to patched versions of the linux-hwe-edge kernel. Users should upgrade to fixed kernel versions corresponding to their distribution. No additional mitigation steps are indicated beyond applying the official patch.
Description
A vulnerability in the Linux kernel's drm/msm component was resolved that involved improper cleanup of partially initialized ring buffers when scheduler initialization failed. The issue caused the scheduler finalization function to be called even if the scheduler was not fully initialized, potentially leading to invalid state handling. This was identified through static analysis and manual review. The vulnerability affects specific versions of the linux-hwe-edge kernel and has a medium severity rating.
