### Description

In onPackageAddedInternal of PermissionManagerService.java, there is a possible way to silently grant a permission after a Target SDK update due to a permissions bypass. This could lead to local escalation of privilege after updating an app to a higher Target SDK with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11 Android-12 Android-12L Android-13Android ID: A-221040577
