CVE-2024-21924

Estado: AplazadaAlta (8.2)—

SMM callout vulnerability within the AmdPlatformRasSspSmm driver could allow a ring 0 attacker to modify boot services handlers, 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.

Vulnerabilidad local (AV:L) sin interacción requerida que escalona desde ring 0 a modificación de handlers de boot, permitiendo ejecución arbitraria de código con privilegios máximos. CWE-250 confirma uso de privilegios elevados.

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.
