CVE-2021-37059Network attack vector

Unspecified impact from undisclosed design weakness

Published Dec 7, 2021 · Updated Aug 4, 2024

Design weakness in Huawei HarmonyOS 2.0 allows remote attackers to cause an unspecified impact via unspecified vectors. Huawei's bulletin and the CNA record do not identify the affected component or disclose the incorrect operation performed on untrusted input. NVD assesses network reachability without authentication or user interaction, but available records establish no more specific consequence or exposure condition.
