CVE-2026-47493

Estado: Pendiente de análisisAlta (7.8)—

NVIDIA vGPU software for Windows and Linux contains a vulnerability in the GPU kernel driver where a guest may access privileged host GPU resources for which it is not authorized. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, denial of service, and information disclosure.

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.

AV:L con PR:L indica explotación local (T1068). La vulnerabilidad en el driver GPU permite acceso no autorizado a recursos de host, causando ejecución de código, escalada de privilegios e información disclosure.

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.
