A trio of boffins at Singapore University this week disclosed 12 security vulnerabilities affecting the Bluetooth Low Energy (BLE) SDKs offered by seven system-on-a-chip (SoC) vendors.


The flaws, collectively dubbed SWEYNTOOTH (because every bug has to have its own name these days), allow a suitably skilled attacker to crash or deadlock BLE devices, or to bypass pairing security to gain arbitrary read and write access to device functions.


The bug branding epithet comes from Sweyn Forkbeard, the son of King Harald "Bluetooth" Gormsson, the namesake of the wireless specification.


"SWEYNTOOTH potentially affects IoT products in appliances such as smart-homes, wearables and environmental tracking or sensing," explain Matheus E. Garbelini, Sudipta Chattopadhyay, and Chundong Wang, in a
