What to do
AI-suggested
A fix has been applied in the Linux kernel source code (commit 71d61e3e299a17139e47f980a4d6f425b2c59bf7) that removes the explicit free and relies on devm-managed cleanup. Users should update to a Linux kernel version that includes this fix once available. No other mitigation steps are indicated.
Description
A double-free vulnerability in the Linux kernel's drm/xe/gsc component was fixed. The issue occurred in the error path of xe_gsc_init_post_hwconfig(), where a buffer object (BO) allocated with xe_managed_bo_create_pin_map() was explicitly freed despite already having a devm cleanup action registered. This caused a double-free during probe failure. The fix removes the explicit free and relies on devm to handle cleanup, aligning with other callers.
