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

HighCVSS 8.4 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 33/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 499be4b5d64209e9f18c9442f9fbeef7155ae900, a4208d8032abd7f591581994f31e23b80b8fe659, adc7dda728ca3e340a413e3bbc10cf159e1866a4.

Low priority for now. Upgrade to Linux Linux 499be4b5d64209e9f18c9442f9fbeef7155ae900, a4208d8032abd7f591581994f31e23b80b8fe659, adc7dda728ca3e340a413e3bbc10cf159e1866a4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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)
