CVE-2024-56439

Sensitive-data disclosure via undisclosed access-control failure

Published Jan 8, 2025 · Updated Sep 18, 2025

Access-control failure in the identity authentication module in Huawei HarmonyOS 5.0.0 allows local users to read sensitive data. Huawei identifies missing encryption of sensitive data but has not disclosed the affected interface, storage or transmission path, or the access-control operation that fails. Exploitation requires high privileges and high attack complexity on a device, and the reported consequence is disclosure rather than service interruption.
