CVE-2023-52388Network attack vector

Unauthenticated service interruption via clock permission failure

Published Apr 8, 2024 · Updated Mar 13, 2025

A permission control weakness in Huawei EMUI and HarmonyOS allows remote attackers to interrupt service through the clock module. The clock module improperly enforces permissions, but Huawei has not disclosed the affected operation, untrusted input, or request path. CISA assesses that no authentication or user interaction is required; the documented consequence is availability loss, with no reported data exposure or modification.
