CVE-2023-39382Network attack vector

VM restart via improper audio input validation

Published Aug 13, 2023 · Updated Oct 10, 2024

Improper input validation in Huawei EMUI and HarmonyOS audio modules allows remote attackers to restart virtual machines. Huawei has not disclosed the affected function or API, the malformed input accepted, or how processing that input reaches the restart condition. Network access requires no authentication or user interaction, and the documented consequence is limited to availability through VM restart.
