CVE-2024-53133

Estado: ModificadaAlta (7.8)—

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

drm/amd/display: Handle dml allocation failure to avoid crash

[Why] In the case where a dml allocation fails for any reason, the current state's dml contexts would no longer be valid. Then subsequent calls dc_state_copy_internal would shallow copy invalid memory and if the new state was released, a double free would occur.

[How] Reset dml pointers in new_state to NULL and avoid invalid pointer

(cherry picked from commit bcafdc61529a48f6f06355d78eb41b3aeda5296c)

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 de escalada local (AV:L, PR:L) en kernel sin interacción (UI:N) que permite al atacante con permisos locales causar DoS mediante doble liberación de memoria en asignación de contextos DML en amd/display.

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.
