Positive Technologies (AI Summary)

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains an issue within the drm/xe/guc subsystem related to stack depot usage. Specifically, a missing stack depot init() call when CONFIG DRM XE DEBUG GUC is enabled can lead to a kernel NULL pointer dereference. This occurs during the execution of the drm sched run job work workqueue, triggered by the stack depot save flags function. The issue was addressed by adding the missing stack depot init() call, as cherry-picked from commit 64fdf496a6929a0a194387d2bb5efaf5da2b542f.
