Alarm cancellation via unprotected exported broadcast receiver
Published Mar 7, 2026 · Updated Mar 7, 2026
Improper authorization in Freedom Factory dGEN1 20260221 allows local users to cancel alarms through an unprotected broadcast receiver. The exported com.dgen.alarm.service.StopReceiver accepts broadcasts without a permission or caller-identity check, then stops AlarmService, dismisses its notification, and cancels the scheduled alarm. A malicious application must be installed on the same device; no special Android permission or user interaction is required, and the demonstrated consequence is loss of alarm availability rather than data access or privilege escalation.
