CVE-2023-21026

Estado: ModificadaMedia (5.5)—

En updateInputChannel de WindowManagerService.java, existe una posible forma de establecer una región táctil más allá de su propio SurfaceControl debido a un error lógico en el código. Esto podría provocar una denegación de servicio local sin que se necesiten privilegios de ejecución adicionales. No se necesita interacción del usuario para la explotación.Product: AndroidVersions: Android-13Android ID: A-254681548
