CVE-2022-38982Network attack vector

Device unlock bypass via fingerprint service logic error

Published Oct 14, 2022 · Updated May 15, 2025

Improper authentication in Huawei HarmonyOS 2.0 allows remote attackers to bypass the phone lock through the fingerprint module. Huawei identifies a service logic error in the fingerprint module but has not disclosed the affected function or the validation step performed incorrectly. Network reachability is the stated gate; successful exploitation defeats the device lock, while post-unlock actions remain unspecified.
