Name of the Vulnerable Software and Affected Versions Android versions Android-13

Description The issue is related to a permissions bypass in the registerReceiverWithFeature method of ActivityManagerService.java. This could allow isolated processes to register a broadcast receiver, potentially leading to local escalation of privilege without requiring additional execution privileges. User interaction is not necessary for exploitation.

Recommendations For Android version Android-13, consider restricting access to the registerReceiverWithFeature method of ActivityManagerService.java to prevent isolated processes from registering broadcast receivers until a patch is available.
