CVE-2026-28542

Service interruption via permission bypass

Published Mar 5, 2026 · Updated Mar 5, 2026

Permission bypass in Huawei EMUI 13.0.0, 14.0.0, and 14.2.0 and HarmonyOS 3.1.0, 4.0.0, and 4.2.0 allows local users to interrupt services. Huawei has not disclosed the specific system service framework locus or the operation that incorrectly bypasses permission enforcement. Local access is required; Huawei reports no required privileges, while NVD assesses low privileges, and the documented consequence is a service interrupt.
