What is CVE-2026-72360?
CVE-2026-72360 is a high-severity denial of service vulnerability in Linux, published on 15 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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)
