CVE-2024-54110

Local screen-content disclosure via cross-process stacking

Published Dec 12, 2024 · Updated Sep 18, 2025

Improper UI-layer restriction in Huawei HarmonyOS 5.0.0 allows local users to read confidential screen content via cross-process stacking. The UIExtension module fails to restrict how screen layers or frames from separate processes are stacked, but Huawei has not disclosed the responsible function or input. Exploitation requires local execution on an affected phone or tablet and is limited to confidentiality, with no reported integrity or availability impact.
