CVE-2022-44553Network attack vector

Periodic third-party app activation via missing filtering

Published Nov 9, 2022 · Updated May 1, 2025

Improper input validation in Huawei HarmonyOS 2.0 through 2.1 and EMUI 11.0.1 through 12.0.1 allows remote attackers to activate apps. When HiView traverses calls to the system provider, it fails to filter third-party applications from the invocation set. No authentication or user interaction is required; the bounded reported consequence is repeated activation of third-party apps.
