CVE-2023-29740Public exploit

Alarm interruption via flooded SET_ALARM broadcasts

Published May 30, 2023 · Updated Jan 14, 2025

Denial of service in Smart Alarm Clock Team Alarm Clock for Heavy Sleepers 5.3.2 allows attackers to interrupt alarms through crafted broadcasts. The ApiCalls component accepts explicit SET_ALARM broadcasts, and the proof of concept floods it with randomized, oversized extras that drive repeated database changes. Another app on the same Android device can trigger the condition without user interaction, disrupting alarm availability.
