CVE-2026-3670Public exploit

Local denial of service via unguarded alarm triggers

Published Mar 7, 2026 · Updated Mar 7, 2026

Improper authorization in Freedom Factory dGEN1 20260221 allows local users to cause persistent alarm playback and denial of service. The exported com.dgen.alarm.receiver.AlarmReceiver performs no calling-UID, package, or signature validation and starts a new looping MediaPlayer for every crafted alarm broadcast without a re-entry guard. Exploitation requires a local application on the device; repeated broadcasts create overlapping playback that disrupts normal device use.
