CVE-2025-37869

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

drm/xe: Use local fence in error path of xe_migrate_clear

The intent of the error path in xe_migrate_clear is to wait on locally

generated fence and then return. The code is waiting on m->fence which

could be the local fence but this is only stable under the job mutex

leading to a possible UAF. Fix code to wait on local fence.

(cherry picked from commit 762b7e95362170b3e13a8704f38d5e47eca4ba74)
