CVE-2025-53177

Schedule synchronization disruption via permission bypass

Published Jul 7, 2025 · Updated Jul 7, 2025

Permission bypass in Huawei HarmonyOS 4.0.0, 4.2.0, and 4.3.0 and EMUI 14.0.0 allows local users to disrupt watch schedule syncing. Huawei identifies the calendar storage module but has not disclosed the code locus or the incorrect permission operation performed on untrusted input. Low-privileged local access and user interaction are required, and the reported consequence is limited to impaired schedule synchronization.
