CVE-2026-47495

Estado: Pendiente de análisisAlta (7.8)—

NVIDIA vGPU Virtual GPU Manager for Windows and Linux contains a vulnerability in the kernel mode layer where a user could cause an out-of-bounds write. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering.

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-787 (out-of-bounds write) en kernel mode con PR:L permite escalada local (T1068) hacia ejecución arbitraria (T1059), DoS (T1499.004) y lectura de memoria (T1005); impacto C:H I:H A:H confirma los tres.

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.
