CVE-2025-11638

Service interruption via exposed Bluetooth GATT command

Published Oct 12, 2025 · Updated Oct 12, 2025

Denial of service in Tomofun Furbo 360 and Furbo Mini allows physically proximate attackers to interrupt camera service. An unauthenticated Bluetooth Low Energy client can write a command to an exposed GATT characteristic, placing the camera in a soft-reset state. Furbo 360 FB0035_FW_036 and earlier and Furbo Mini MC0020_FW_074 and earlier drop Wi-Fi and remain unusable until manually power-cycled.
