CVE-2025-40111

Estado: AplazadaAlta (7.8)—

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

drm/vmwgfx: Fix Use-after-free in validation

Nodes stored in the validation duplicates hashtable come from an arena allocator that is cleared at the end of vmw_execbuf_process. All nodes are expected to be cleared in vmw_validation_drop_ht but this node escaped because its resource was destroyed prematurely.

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 local (AV:L) sin interacción (UI:N) con privilegios (PR:L) en kernel Linux. Use-after-free puede causar DoS (crash) o escalada de privilegios. Acceso local con efectos de confidencialidad, integridad y disponibilidad altos (C:H, I:H, A:H).

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.
