CVE-2023-52113Network attack vector

Unauthenticated service interruption

Published Jan 16, 2024 · Updated Jun 20, 2025

Uncaught exception handling in Huawei HarmonyOS and EMUI allows remote attackers to interrupt device service via launchAnyWhere. Huawei identifies ActivityManagerService as the affected module but has not published the operation that mishandles attacker-controlled input. Exploitation is unauthenticated and network-reachable, and the documented consequence is limited to availability; the precise failure mode is undisclosed.
