Summary

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

drm/xe: Return error on non-migratable faults requiring devmem

Non-migratable faults that require devmem incorrectly jump to the 'out' label, which squashes the error code intended to be returned to the upper layers. Fix this by returning -EACCES instead.

(cherry picked from commit c4508edb2c723de93717272488ea65b165637eac)
