Two vulnerabilities in Bluetooth chips allow attackers to take control of devices without authentication or to breach the network. The vulnerable chips are also present in medical devices (insulin pumps, pacemakers), smart locks and a variety of other types of products that rely on Bluetooth Low Energy (BLE) technology for communication. Cisco, Meraki and Aruba Networks sell at least 70% of the WiFi service in enterprises every year. Texas Instruments prepared a fix for the bug, which is available in version 2.2.2.
