CVE-2026-49173

Estado: AnalizadaAlta (7.8)—

Use after free in Windows Kernel allows an authorized attacker to elevate privileges locally.

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.

CWE-416 (use after free) en kernel de Windows con AV:L y PR:L permite escalada de privilegios local sin interacción. Acceso local + escalada = T1068. Impacto: ejecución de código con privilegios elevados (T1059).

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.
