CVE-2022-22255Network attack vector

Unauthenticated service interruption via undisclosed framework flaw

Published Apr 11, 2022 · Updated Aug 3, 2024

Denial of service in Huawei HarmonyOS 2.0 and EMUI 12.0.0 allows remote attackers to interrupt service through the application framework. Huawei has not published the affected function, input, or operation within the framework that triggers the denial of service. Network access without authentication or user interaction is sufficient, and the documented consequence is limited to availability.
