CVE-2024-39081Public exploit

False tire alerts via replayed Bluetooth broadcasts

Published Sep 18, 2024 · Updated Mar 17, 2025

Authentication bypass in SMART TYRE CAR & BIKE 4.2.0 allows physically proximate attackers to inject false tire alerts over Bluetooth. The app accepts replayed or manipulated TPMS Bluetooth Low Energy sensor data without authenticating its source or freshness, and displays the forged readings as valid alerts. An attacker must be within Bluetooth range of the vehicle, and the demonstrated consequence is false pressure-related warnings rather than device takeover or service interruption.
