In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Use local fence in error path of xemigrateclear
The intent of the error path in xemigrateclear 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.
