GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

CVE-2021-31786 (GCVE-0-2021-31786)

Vulnerability from cvelistv5 – Published: 2021-09-07 06:05 – Updated: 2024-08-03 23:10
VLAI
Summary
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.
