Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/xe: Don&amp;#39;t free job in TDR<br /> <br /> Freeing job in TDR is not safe as TDR can pass the run_job thread<br /> resulting in UAF. It is only safe for free job to naturally be called by<br /> the scheduler. Rather free job in TDR, add to pending list.<br /> <br /> (cherry picked from commit ea2f6a77d0c40d97f4a4dc93fee4afe15d94926d)
