CVE-2024-49865

Estado: ModificadaAlta (7.8)—

In the Linux kernel, the following vulnerability has been resolved:

drm/xe/vm: move xa_alloc to prevent UAF

Evil user can guess the next id of the vm before the ioctl completes and then call vm destroy ioctl to trigger UAF since create ioctl is still referencing the same vm. Move the xa_alloc all the way to the end to prevent this.

v2: - Rebase

(cherry picked from commit dcfd3971327f3ee92765154baebbaece833d3ca9)

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.

Acceso local (AV:L) sin interacción (UI:N) en kernel Linux permite escalada de privilegios (C:H/I:H/A:H) mediante race condition (UAF) en vm ioctl, logrando ejecución de código con permisos elevados.

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.
