CVE-2023-44101Network attack vector

Information disclosure via Bluetooth broadcast permission failure

Published Oct 11, 2023 · Updated Sep 18, 2024

Permission-control failure in Huawei HarmonyOS 2.0.0, 2.1.0, 3.1.0, and 4.0.0 allows remote attackers to disclose Bluetooth notification data. The Bluetooth module exposes broadcast notifications without enforcing the intended permission boundary; Huawei has not identified the responsible function or request path. Network access without authentication or user interaction is sufficient, and the documented consequence is limited to confidentiality.
