Description OSIDB Bzimport 2026-08-15 06:17:44 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/xe/pf: Don't attempt to process FAST_REQ or EVENT relays

Currently defined VF/PF relay actions use regular REQUEST messages
only and the PF shouldn't attempt to handle FAST_REQUEST nor EVENT
messages as this would result in breaking the VFPF ABI protocol
and also might trigger an assert on the PF side.

(cherry picked from commit 1714d360fc5ae2e0886a69e979095d9c7ff3568a)
