Estado: ModificadaAlta (7.8)—

En múltiples funciones de looper_backed_event_loop.cpp, existe una posible forma de corromper la memoria debido a un bloqueo inadecuado. Esto podría dar lugar a una escalada de privilegios local sin que se necesiten privilegios de ejecución adicionales. No se requiere interacción del usuario para la explotación.Product: AndroidVersions: Android-12 Android-12L Android-13Android ID: A-243362981
