CVE-2023-52362Network attack vector

Unauthenticated device availability interruption

Published Feb 18, 2024 · Updated Oct 28, 2024

Permission management in Huawei HarmonyOS 3.0.0, 3.1.0, and 4.0.0 and EMUI 13.0.0 allows remote attackers to interrupt device availability. The lock screen module mishandles permissions, but Huawei has not published the affected function, permission, or triggering input. No authentication or user interaction is required; the public record does not specify whether exploitation causes a hang, crash, reboot, or shutdown.
