Local data disclosure and service interruption

Published Apr 13, 2026 · Updated Apr 13, 2026

Improper access control in the HarmonyOS memo module in 5.1.0 and 6.0.0 allows local users to read data and interrupt service. Huawei has not disclosed the memo-module operation that fails to enforce access control or the input that reaches it. Exploitation requires local access, high-complexity conditions, and user interaction but no prior privileges; reported impact is limited to confidentiality and availability.
