Descriptions

In the Linux kernel, the following vulnerability has been resolved:

drm/xe: Don't free job in TDR

Freeing job in TDR is not safe as TDR can pass the run_job thread
resulting in UAF. It is only safe for free job to naturally be called by
the scheduler. Rather free job in TDR, add to pending list.

(cherry picked from commit ea2f6a77d0c40d97f4a4dc93fee4afe15d94926d)

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/xe: No liberar trabajo en TDR Liberar trabajo en TDR no es seguro, ya que TDR puede pasar el subproceso run_job, lo que genera una UAF. Solo es seguro que el programador llame naturalmente al trabajo libre. En lugar de liberar trabajo en TDR, agréguelo a la lista de pendientes.
