Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/i915: mark requests for GuC virtual engines to avoid use-after-free<br />
<br />
References to i915_requests may be trapped by userspace inside a<br />
sync_file or dmabuf (dma-resv) and held indefinitely across different<br />
proceses. To counter-act the memory leaks, we try to not to keep<br />
references from the request past their completion.<br />
On the other side on fence release we need to know if rq->engine<br />
is valid and points to hw engine (true for non-virtual requests).<br />
To make it possible extra bit has been added to rq->execution_mask,<br />
for marking virtual engines.<br />
<br />
(cherry picked from commit 280410677af763f3871b93e794a199cfcf6fb580)
