CVE-2026-47497

Estado: Pendiente de análisisAlta (7.8)—

NVIDIA Virtual GPU Manager contains a vulnerability in the GPU System Processor (GSP) tracing component where a guest VM user may cause improper access by sending crafted data through a shared buffer. 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/PR:L indica acceso local con privilegios limitados; CWE-367 (race condition/improper access) en componente GSP permite escalada. Impactos: ejecución (code execution), manipulación (data tampering), exfiltración (information disclosure) confirmados en 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.
