CVE-2026-41966Network attack vector

Unauthenticated smart sensing service data exposure

Published May 15, 2026 · Updated May 15, 2026

Permission control failure in Huawei HarmonyOS 5.1.0, 6.0.0, and 6.1.0 allows remote attackers to expose smart sensing service data. Huawei identifies the locus as the smart sensing service but has not disclosed which permission check is missing or what data the service exposes. Network access requires no privileges or user interaction, but high attack complexity applies; the documented consequence is exposure affecting service confidentiality.
