CVE-2025-64312

Data exposure via improper permission enforcement

Published Nov 28, 2025 · Updated Nov 28, 2025

Permission control failure in Huawei HarmonyOS 5.0.1, 5.1.0, and 6.0.0 allows physically proximate attackers to expose service data. The file management module improperly enforces permissions, but Huawei has not disclosed the affected operation, data path, or input that triggers the check failure. Exploitation requires physical access and user interaction, and the documented consequence is unauthorized data exposure with no availability impact.
