Device reboot via malformed BLE characteristic writes
Published May 9, 2024 · Updated Mar 13, 2025
Denial of service in Nuki Smart Lock 3.0 before 3.3.5 and 2.0 before 2.12.4 allows physically proximate attackers to reboot the lock via BLE. An unauthenticated long malformed write to BLE GATT characteristic handle 0x69 triggers the failure, and repeated writes ensure the reboot. Bluetooth proximity is required, and the observed consequence is instability, loss of some lock functionality, and a device reboot.
