CVE-2026-20495

Estado: AnalizadaAlta (7.8)—

In Bluetooth driver, there is a possible permission bypass due to a missing permission check. This could lead to local escalation of privilege with User execution privileges needed. User interaction is not needed for exploitation. Patch ID: WCNCR00488300; Issue ID: MSV-7296.

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.

Vector AV:L/PR:L sin UI:R indica escalada local sin interacción (T1068). CWE-862 es falta de validación de permisos. Impactos: obtención de privilegios elevados (T1078) y potencial ejecución de código con permisos superiores (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.
