CVE-2024-43631

Estado: AnalizadaAlta (7.8)—

Windows Secure Kernel Mode Elevation of Privilege Vulnerability

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 7.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.54%
Percentil entre todas las CVEs puntuadas: 44
Fecha de la puntuación: 6/10/2026

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.

ExplotaciónT1068 Exploitation for Privilege Escalationprivilege escalation95 %
Impacto principalT1548 Abuse Elevation Control Mechanismprivilege escalation85 %
Impacto secundarioT1059 Command and Scripting Interpreterexecution75 %

Vector CVSS AV:L/PR:L sin UI:R indica acceso local sin interacción (T1068). La vulnerabilidad en Secure Kernel Mode permite escalada de privilegios (C:H/I:H/A:H en S:U sugiere control completo del sistema), derivando en T1548 (elevación) y potencial T1059 (ejecución de comandos con privilegios).

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.
