CVE-2023-31323

Estado: AplazadaAlta (8.4)—

Type confusion in the AMD Secure Processor (ASP) could allow an attacker to pass a malformed argument to the External Global Memory Interconnect Trusted Agent (XGMI TA) leading to a memory safety violation potentially resulting in loss of confidentiality, integrity, or availability.

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 sin UI:R indica acceso local sin interacción (T1068). Type confusion en procesador seguro permite ejecución de código (T1059) y acceso a memoria (T1005); VI:H e SI:H confirman integridad/disponibilidad comprometidas.

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.
