CVE-2024-56437

Service interruption via unverified widget parameters

Published Jan 8, 2025 · Updated Jan 8, 2025

Improper input validation in the widget framework in Huawei HarmonyOS 5.0.0 allows attackers to interrupt service via widget input. The framework fails to verify input parameters, but Huawei has not identified the affected interface, parameter, or resulting failure mode. Exploitation requires adjacent access and user interaction; the reported consequence is limited to availability.
