Researchers have disclosed a group of 16 different vulnerabilities collectively dubbed BrakTooth, which impact billions of devices that rely on Bluetooth Classic (BT) for communication.
According to an academic paper from the University of Singapore, the bugs are found in the closed commercial BT stack used by at least 1,400 embedded chip components, that can lead to a host of attack types – mainly denial of service (DoS) via firmware crashes (the term “brak” is actually Norwegian for “crash”). One of the bugs can also lead to arbitrary code execution (ACE).
