12 vulnerabilities were found across different BLE software development kits (SDKs) of six major system-on-a-chip (SoC) vendors. The vulnerabilities expose flaws in specific BLE SoC implementations that allow an attacker in radio range to trigger deadlocks, crashes and buffer overflow or completely bypass security depending on the circumstances.

The researchers also made available the proof of concept code on their GitHub repository: https://github.com/Matheus-Garbelini/sweyntooth_bluetooth_lo...
