CVE-2026-69293

Estado: AnalizadaAlta (7.8)—

Heap-based buffer overflow in Windows Biometric Service 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.

AV:L sin UI:R → T1068. Buffer overflow en servicio permite escalada de privilegios local. Ejecución de código con permisos elevados (T1059) y potencial acceso a cuentas SYSTEM (T1078.001).

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.
