CVE-2025-48908

Service disruption via unsynchronized auto-start data

Published Jun 6, 2025 · Updated Jun 9, 2025

Improper synchronization in Huawei HarmonyOS 5.0.0 and 5.0.2 allows local users with high privileges to disrupt the Ability Auto Startup service. The foundation process's Ability Auto Startup service accesses shared data without the synchronization required for concurrent execution. Exploitation requires local access and high privileges; Huawei has not disclosed the trigger, affected shared object, or whether disruption causes a hang, crash, or restart.
