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

Description The issue is related to a missing permission check in the onReceive method of AlertReceiver.java. This could allow for the dismissal of system dialogs, potentially leading to local escalation of privilege without requiring additional execution privileges. User interaction is not necessary for exploitation.

Recommendations For Android versions prior to the fixed version, consider restricting access to the AlertReceiver.java module to minimize the risk of exploitation until a patch is available.
