CVE-2023-52364Network attack vector

Authenticated memory corruption via unchecked RSMC parameters

Published Apr 8, 2024 · Updated Nov 1, 2024

Buffer overflow in Huawei HarmonyOS 3.0.0, 3.1.0, and 4.0.0 and EMUI 13.0.0 allows remote authenticated users to write out of bounds. The RSMC module fails to validate input parameters strictly before copying them into a bounded buffer, allowing the write to exceed that buffer. Network access with low privileges is required, and the resulting memory corruption can affect confidentiality, integrity, and availability.
