CVE-2025-61972

Estado: Pendiente de análisisAlta (8.5)—

Missing lock bit protection for NBIO registers could allow a local admin-privileged attacker to gain arbitrary System Management Network (SMN) access, potentially resulting in arbitrary code execution in AMD Secure Processor (ASP) and loss of the SEV-SNP guest's confidentiality and integrity.

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 con privilegios elevados (PR:H, AV:L) sin interacción permite escalada en procesador AMD. Explotación de CWE-1233 (falta de protección lock bit) resulta en ejecución de código arbitrario en ASP, alteración de integridad y pérdida de confidencialidad de SEV-SNP.

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.
