CVE-2022-47974

Bluetooth service interruption via undisclosed AVRCP flaw

Published Jan 6, 2023 · Updated Apr 9, 2025

AVRCP denial of service in Huawei HarmonyOS 2.0, 2.1, 3.0.0 and EMUI 11.0.1, 12.0.0, 12.0.1 lets attackers restart Bluetooth. Huawei identifies the Bluetooth AVRCP module but has not disclosed the malformed input, parsing path, or incorrect operation that triggers the restart. The attack requires adjacent Bluetooth reachability and no prior privileges; the bounded consequence is interruption of Bluetooth until its process restarts.
