Security experts have discovered multiple flaws, dubbed SweynTooth, in the Bluetooth Low Energy (BLE) implementations of major system-on-a-chip (SoC) vendors. The group was composed of researchers Matheus E. Garbelini, Sudipta Chattopadhyay, and Chundong Wang from the Singapore University of Technology and Design. The vulnerabilities expose flaws in specific BLE SoC implementations that allow an attacker in radio range to trigger deadlocks, crashes and. completely bypass security depending on the circumstances.”]
