Estado: ModificadaMedia (6.8)—

En (TBD) de (TBD), existe una forma posible de omitir la pantalla de bloqueo debido a una falla de autenticación biométrica. Esto podría conducir a una escalada local de privilegios con acceso físico al dispositivo sin necesidad de permisos de ejecución adicionales. No se necesita la interacción del usuario para la explotación.Producto: AndroidVersiones: kernel de AndroidID de Android: A-240428519Referencias: N/A

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).
