AI-suggested

A patch is available and has been applied in Linux kernel versions 7.0.0 and later as listed. Users should upgrade to these fixed kernel versions to remediate the vulnerability. No additional mitigation actions are required beyond applying the official fix.

Description

A double-free vulnerability was identified and fixed in the Linux kernel's drm/xe/gsc driver. The issue occurs in the error handling path of xe_gsc_init_post_hwconfig(), where a managed buffer object (BO) is explicitly freed despite already having a devm cleanup action registered, leading to a double-free scenario. This flaw has been corrected by removing the explicit free and relying on devm to manage cleanup, consistent with other similar calls.
