Description OSIDB Bzimport 2024-09-04 20:21:27 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/xe: Free job before xe_exec_queue_put

Free job depends on job->vm being valid, the last xe_exec_queue_put can
destroy the VM. Prevent UAF by freeing job before xe_exec_queue_put.

(cherry picked from commit 32a42c93b74c8ca6d0915ea3eba21bceff53042f)
