CVE-2024-56454

Local service interruption via unchecked glTF copy

Published Jan 8, 2025 · Updated Jan 8, 2025

Buffer overflow in the 3D engine module in Huawei HarmonyOS 5.0.0 allows local users to interrupt service through a crafted glTF model. During glTF model loading, the module copies input into a destination buffer without verifying that the input fits. Low-privilege local access is required, and the published impact is limited to availability; Huawei has not disclosed the exact parser routine.
