CVE-2023-52552Network attack vector

Service interruption from invalid power-module input

Published Apr 8, 2024 · Updated Aug 20, 2024

Improper input validation in Huawei HarmonyOS 2.1.0, 3.0.0, 3.1.0, and 4.0.0 and EMUI 13.0.0 allows remote attackers to interrupt service. The power module fails to verify some input, but Huawei has not disclosed the input path, rejected value, or resulting failure mode. No privileges or user interaction are required; the published impact is limited to availability, without a stated distinction among a hang, crash, reboot, or shutdown.
