CVE-2025-54628Network attack vector

Service interruption via incomplete communication-data verification

Published Aug 6, 2025 · Updated Aug 6, 2025

Incomplete verification in the communication module of affected Huawei HarmonyOS and EMUI releases allows remote attackers to interrupt service. Huawei maps the flaw to incorrect access of an indexable resource, but has not disclosed the input, code locus, or exact failure mode. Network reachability without authentication or user interaction is sufficient, and the published impact is limited to availability.
