In startActivityInner of ActivityStarter.java, there is a possible way to launch an activity into PiP mode from the background due to BAL bypass. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
