CVE-2024-56451
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInteger overflow vulnerability during glTF model loading in the 3D engine module Impact: Successful exploitation of this vulnerability may affect availability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceInteger overflow vulnerability exists in the 3D engine module during glTF model file parsing. When processing malformed or crafted glTF files, the overflow can cause memory corruption leading to application instability or crash, impacting system availability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check HarmonyOS versionRun 'getprop ro.build.version.sdk' or check system settings > About Device to confirm the exact HarmonyOS version numberAffected if Version is exactly 5.0.0 (exact match required)
-
Identify 3D engine module presenceCheck system logs or application manifest for presence of 3D rendering engine components (typically named '3d', 'render', or 'gltf' in module listings)Affected if 3D engine module is loaded or available on the system
-
Verify glTF parsing capabilityInspect installed applications or services that handle 3D model loading. Look for apps with 3D model viewer functionality or check if glTF libraries are present in the system (/system/lib or /vendor/lib directories)Affected if glTF model parsing capability exists or any application uses glTF loading functionality
-
Check for model processing activityMonitor system for processes that load or parse 3D model files. Use 'ps -A' or system process monitor to identify apps importing 3D contentAffected if Any application or service that processes glTF files is running or has been used
System is affected only if HarmonyOS version equals exactly 5.0.0 AND the 3D engine module with glTF parsing capability is present and actively used on the device

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper integer overflow checks and boundary validation in the glTF model loading code path before any memory allocation or indexing operations.
