CVE-2021-31786

The Bluetooth Classic Audio implementation on Actions ATS2815 and ATS2819 devices does not properly handle a connection attempt from a host with the same BDAddress as the current connected BT host, allowing attackers to trigger a disconnection and deadlock of the device by connecting with a forged BDAddress that matches the original connected host.
