CVE-2026-22163

Estado: AnalizadaAlta (7.8)—

Requires malware code to misuse the DDK kernel module IOCTL interface.

Such code can use the interface in an unsupported way that allows subversion of the GPU to perform writes to arbitrary physical memory pages.

The product utilises a shared resource in a concurrent manner but does not attempt to synchronise access to the resource.

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.

Acceso local (AV:L) con PR:L sin interacción (UI:N) → T1068. El abuso del módulo kernel DDK permite escrituras en memoria física arbitraria (T1565.001) y subversión del GPU para obtener privilegios elevados (T1548).

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.
