In onParentVisible of HeaderPrivacyIconsController.kt, there is a possible way to bypass factory reset protections due to a missing permission check. This could lead to local escalation of privilege with physical access to a device that’s been factory reset with no additional execution privileges needed. User interaction is not needed for exploitation.
