CVE-2026-72360

Estado: RecibidaAlta (8.4)—

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)

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad local (AV:L, PR:L) sin interacción del usuario en kernel Linux que permite escalada mediante violación del protocolo VFPF; impacta integridad (I:H) del sistema de gráficos y disponibilidad (A:H) por posible corrupción o DoS.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
