CVE-2025-54650Network attack vector

Audio decoding disruption via unchecked array index

Published Aug 6, 2025 · Updated Aug 6, 2025

Improper array index validation in Huawei HarmonyOS 5.0.1 and 5.1.0 allows remote attackers to affect audio decoding. The audio codec module uses an array index without adequate verification before accessing codec data during decoding. Exploitation requires high complexity and user interaction; Huawei does not disclose the codec entry point or the exact decoding failure.
