CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

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.
