CVE-2026-53054

Estado: AnalizadaAlta (7.8)—

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

drm/msm: Fix VM_BIND UNMAP locking

Wrong argument meant that the objs involved in UNMAP ops were not always getting locked.

Since _NO_SHARE objs share a common resv with the VM (which is always locked) this would only show up with non-_NO_SHARE BOs.

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.

CWE-667 (uso incorrecto de sincronización) en driver DRM del kernel con acceso local (AV:L/PR:L) permite escalada de privilegios. La falta de bloqueo en UNMAP podría corromper datos o causar 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.
