CVE-2022-48312Network attack vector

Unauthorized memory read and write via out-of-bounds access

Published Apr 16, 2023 · Updated Feb 6, 2025

Out-of-bounds access in Huawei HwPCAssistant in HarmonyOS 2.0.0 and EMUI 12.0.0 allows remote attackers to read and write memory. Huawei identifies the locus only as the HwPCAssistant module and has not disclosed the affected routine, input, or boundary-check failure. Network access without authentication or user interaction is sufficient, and successful exploitation compromises confidentiality and integrity without a reported availability impact.
