Details

In startActivityForAttachedApplicationIfNeeded of RootWindowContainer.java, there is a possible way to overlay an app that believes it's still in the foreground, when it is not, due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
