Estado: AplazadaAlta (7.8)—

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

drm/xe/guc: Synchronize Dead CT worker with unbind

Cancel and wait for any Dead CT worker to complete before continuing with device unbinding. Else the worker will end up using resources freed by the undind operation.

(cherry picked from commit 492671339114e376aaa38626d637a2751cdef263)

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.

AV:L/PR:L/UI:N indica escalada local. Acceso no sincronizado a recursos liberados (use-after-free) puede causar DoS o corrupción de memoria en kernel.

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.
