CVE-2024-56453

Local denial of service via unchecked glTF input

Published Jan 8, 2025 · Updated Jan 8, 2025

Buffer overflow in Huawei HarmonyOS 5.0.0's 3D engine module allows local users to disrupt device availability via a crafted glTF model. The published CWE-120 mapping identifies an unchecked buffer copy during model loading, but Huawei has not disclosed the affected function or malformed field. Exploitation requires local processing of attacker-controlled model input, and the public record does not distinguish a crash from a hang or other interruption.
