CVE-2023-44102Network attack vector

Bluetooth service interruption via broadcast permission failure

Published Oct 11, 2023 · Updated Sep 18, 2024

Broadcast permission control failure in affected Huawei HarmonyOS and EMUI releases allows remote attackers to interrupt Bluetooth service. The Bluetooth module applies broadcast permissions incorrectly, but Huawei has not disclosed the affected operation, accepted input, or request path. No privileges or user interaction are required according to NVD; successful exploitation makes Bluetooth unavailable without reported data access or modification.
