CVE-2022-48681

Function failure via Bluetooth-triggered memory overflow

Published May 28, 2024 · Updated Aug 3, 2024

Memory overflow in Huawei Sound Joy 2.1.0.20(H100SP30C00) allows attackers to interrupt functions through a Bluetooth connection. Huawei has not disclosed the affected firmware component or the memory operation that fails to bound attacker-controlled input. Exploitation requires a Bluetooth connection, common permissions, high attack complexity, and user interaction; successful attacks execute code and can cause certain speaker functions to fail.
