CVE-2023-34156Network attack vector

Unauthenticated service interruption via fingerprint APIs

Published Jun 19, 2023 · Updated Dec 17, 2024

Denial of service in Huawei HarmonyOS and EMUI allows remote attackers to interrupt services through early fingerprint APIs. Huawei has not published the affected API names or the operation that mishandles input and causes the service interruption. Network access without authentication or user interaction is sufficient; the reported consequence is limited to interrupted services.
