CVE-2022-46762Network attack vector

Data disclosure via memory-management logic bypass

Published Jan 6, 2023 · Updated Apr 9, 2025

Logic bypass in the memory management module in Huawei EMUI 12.0.0 and HarmonyOS 2.0 allows remote attackers to disclose data. Huawei has not published the faulty operation or the untrusted input that bypasses the module's intended protection. Network access without authentication or user interaction is sufficient, and exploitation exposes data without reported modification or service interruption.
