Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/gsc: Fix double-free of managed BO in error path
The error path in xe_gsc_init_post_hwconfig() explicitly frees a BO allocated with xe_managed_bo_create_pin_map() via xe_bo_unpin_map_no_vm(). Since the managed BO already has a devm cleanup action registered, this causes a double-free when devm unwinds during probe failure.
Remove the explicit free and let devm handle it, consistent with all other xe_managed_bo_create_pin_map() callers.
(cherry picked from commit 71d61e3e299a17139e47f980a4d6f425b2c59bf7)
