CVE-2025-54645

Location service interruption via unchecked array index

Published Aug 6, 2025 · Updated Aug 6, 2025

Out-of-bounds array access in Huawei HarmonyOS 5.0.1 and 5.1.0 allows local users to interrupt the location service. The location service module uses an insufficiently validated value as an array index, causing access outside the array bounds. Huawei does not disclose the input path or failure mode; NVD assesses low-privileged local access, while Huawei assesses user interaction without privileges.
