CVE-2022-29789Network attack vector

AI service interruption via invalid model properties

Published May 13, 2022 · Updated Aug 3, 2024

Improper model-property validation in Huawei HiAIserver on HarmonyOS 2.0 and EMUI 12.0.0 allows remote attackers to interrupt AI services. HiAIserver accepts model properties without strict validity checks, causing AI-service exceptions when crafted model data is processed. Public records do not identify the exposed interface or property constraints, and the reported consequence is limited to AI-service interruption.
