CVE-2026-47496

Estado: Pendiente de análisisAlta (7.3)—

NVIDIA GPU Display Driver for Linux contains a vulnerability in the Virtual GPU Manager (vGPU plugin) where a guest VM user may cause an out-of-bounds write by sending a specially crafted RPC call to the host. A successful exploit of this vulnerability might lead to escalation of privileges, data tampering, and denial of service.

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.

Out-of-bounds write desde VM guest con PR:L permite escalada local (T1068). Posibilita ejecución de comandos (T1059.007) en host, DoS (T1499.004) y corrupción de datos (T1565.001) según descripción.

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.
