Description

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.

Affected configurations

• actions-semi ats2819p firmware • actions-semi ats2815 firmware • actions-semi ats2819 firmware • actions-semi ats2819s firmware • actions-semi ats2819t firmware
