CVE-2023-31317

Estado: Pendiente de análisisAlta (8.8)—

Improper restriction of operations within the bounds of a memory buffer in the AMD secure processer (ASP) could allow an attacker to read or write to protected memory potentially resulting in arbitrary code execution.

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 (AV:L) sin interacción (UI:N) con privilegios requeridos (PR:L) permite escalada de privilegios en el procesador seguro AMD. Buffer overflow (CWE-119) posibilita ejecución de código arbitrario y lectura de memoria protegida.

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.
