CVE-2022-46316Network attack vector

System compromise via fingerprint input validation

Published Dec 20, 2022 · Updated Apr 17, 2025

Input validation failure in the fingerprint module of Huawei HarmonyOS 2.1 and 3.0.0 allows remote attackers to compromise the system. Huawei does not disclose the affected thread, reachable interface, or validation operation performed incorrectly on fingerprint input. Network access without authentication or user interaction is sufficient, and exploitation affects confidentiality, integrity, and availability.
