CVE-2023-54254

Estado: AplazadaAlta (7.8)—

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

drm/ttm: Don't leak a resource on eviction error

On eviction errors other than -EMULTIHOP we were leaking a resource. Fix.

v2: - Avoid yet another goto (Andi Shyti)

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.

Vector CVSS AV:L/PR:L/UI:N indica escalada local sin interacción (T1068). Fuga de recurso en TTM/DRM puede causar DoS o corrupción de memoria/datos. Confianza moderada por falta de detalles de explotación.

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.
