In the Linux kernel, the following vulnerability has been resolved:
drm/xe/rtp: Add RING_FORCE_TO_NONPRIV_DENY to OA whitelists
Unconditionally whitelisting OA registers is a security violation. Set
RING_FORCE_TO_NONPRIV_DENY bit in OA nonpriv slots, so that OA registers
don't get whitelisted by default after probe, gt reset, resume and engine
reset.
(cherry picked from commit 90511bdcfda97211c01f1d945d4ea616578d8fca)
