CVE-2023-52378Network attack vector

Abnormal feature behavior via incorrect service logic

Published Feb 18, 2024 · Updated Mar 28, 2025

Business logic error in Huawei HarmonyOS 3.0.0 and 3.1.0 and EMUI 13.0.0 allows remote attackers to trigger abnormal feature behavior. The flaw resides in WindowManagerServices, but Huawei has not disclosed the faulty operation, its input, or the specific violated condition. CISA characterizes the path as unauthenticated and network-reachable, while Huawei limits the published consequence to features operating abnormally.
