Name of the Vulnerable Software and Affected Versions Android versions prior to the fixed version

Description In the registerServiceLocked function of ManagedServices.java, there is a possible bypass of background activity launch restrictions due to an unsafe PendingIntent. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Recommendations For Android versions prior to the fixed version, consider restricting the use of the registerServiceLocked function in ManagedServices.java to minimize the risk of exploitation. As a temporary workaround, avoid using unsafe PendingIntent objects in the affected functionality until a patch is available.
