CVE-2023-21266

Estado: ModificadaAlta (7.8)—

En killBackgroundProcesses de ActivityManagerService.java, existe una forma posible de escapar de la protección de Google Play debido a una omisión de permisos. Esto podría conducir a una escalada local de privilegios sin necesidad de privilegios de ejecución adicionales. La interacción del usuario no es necesaria para la explotación.

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).
