CVE-2024-56451

Service interruption via glTF loading integer overflow

Published Jan 8, 2025 · Updated Jan 8, 2025

Integer overflow in HarmonyOS 5.0.0's 3D engine allows local users to interrupt service by loading a crafted glTF model. Huawei identifies the overflow during model loading but has not disclosed the arithmetic operation, allocation, or parsing field that overflows. Exploitation requires local low-privileged access; published material does not distinguish a hang from a crash, so the consequence is bounded to service interruption.
