CVE-2023-21035

Estado: ModificadaAlta (7.8)—

En varias funciones de BackupHelper.java, existe una posible forma en la que una aplicación pueda obtener permisos concedidos previamente a otra aplicación con el mismo nombre de paquete, debido a una omisión de permisos. Esto podría provocar una escalada de privilegios local sin que se necesiten privilegios de ejecución adicionales. No se necesita interacción del usuario para la explotación.Product: AndroidVersions: Android-13Android ID: A-184847040
