Summary

Isolated apps able to register a broadcast receiver

Details

In registerReceiverWithFeature of ActivityManagerService.java, there is a possible way for isolated processes to register a broadcast receiver due to a permissions bypass. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
