CVE-2024-40885

Estado: AplazadaAlta (8.7)—

Use after free in the UEFI firmware of some Intel(R) Server M20NTP BIOS may allow a privileged user to potentially enable escalation of privilege via local access.

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.

UEFI BIOS con Use-After-Free (CWE-416) requiere acceso local (AV:L) y usuario privilegiado (PR:H), alineado con T1068. El impacto es escalada de privilegios con potencial ejecución de código en firmware.

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.
