Summary
Android 11-12 Normal App Privilege Escalation To ADB Shell
Details

In broadcastPortInfo of AdbService.java, there is a possible way for apps to run code as the shell user, if wireless debugging is enabled, due to a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
