CVE-2022-47976Network attack vector

Service disconnection via imposter control connections

Published Jan 6, 2023 · Updated Apr 9, 2025

Improper authentication in Huawei HarmonyOS 2.0, 2.1, and 3.0.0 and EMUI 12.0.0 allows remote attackers to interrupt services. The distributed-hardware DMSDP module accepts an imposter control connection that replaces a legitimate connection instead of rejecting the unauthenticated peer. No privileges or user interaction are required, and successful exploitation disconnects normal service connections without reported data exposure or modification.
