Details

In updatePublicMode of NotificationLockscreenUserManagerImpl.java, there is a possible way to reveal sensitive notifications on the lockscreen due to an incorrect state transition. This could lead to local information disclosure with physical access required and an app that runs above the lockscreen, with no additional execution privileges needed. User interaction is not needed for exploitation.
