CVE-2024-37026
Description
In the Linux kernel, the following vulnerability has been resolved:drm/xe: Only use reserved BCS instances for usm migrate exec queueThe GuC context scheduling queue is 2 entires deep, thus it is possiblefor a migration job to be stuck behind a fault if migration exec queueshares engines with user jobs. This can deadlock as the migrate execqueue is required to service page faults. Avoid deadlock by only usingreserved BCS instances for usm migrate exec queue.(cherry picked from commit 04f4a70a183a688a60fe3882d6e4236ea02cfc67)
