CVE-2026-72360
drm/xe/pf: Don't attempt to process FAST_REQ or EVENT relays
Description
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)
