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 · unedited
Vulnerability of input parameters not being verified 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 confidence

The vulnerability stems from missing input validation on parameters during glTF model loading in the 3D engine module. A specially crafted malicious glTF file could cause the engine to crash, hang, or exhaust resources due to unvalidated input values being processed, leading to availability impact.

MitigationImplement comprehensive input validation and bounds checking on all glTF parameters (mesh counts, array sizes, buffer lengths, etc.) before processing the model data.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify HarmonyOS version
    Check the system version by going to Settings > About Device > Version on the HarmonyOS device, or use the 'getprop ro.build.version.harmonyos' command via ADB
    Affected if Version is exactly 5.0.0
  2. Verify 3D engine module presence
    Check for installed applications that use 3D rendering engines, or inspect system modules for 3D engine components (common paths include /system/lib/ or /system/lib64/ with names containing '3d', 'render', or 'engine')
    Affected if 3D engine module is present on the device
  3. Identify glTF model loading usage
    Review installed applications for those that load or parse glTF/glb 3D model files. Check application permissions and capabilities for 3D model processing. Monitor network traffic or file access for .gltf or .glb file operations
    Affected if Applications that load or process glTF models are in use
  4. Check for unvalidated input processing
    Examine application logs or system traces for any errors related to glTF parsing, mesh loading, or buffer processing. Look for crash reports mentioning 'gltf', 'mesh', or 'buffer' in the stack trace
    Affected if GlTF model loading is actively used and no additional input validation layer is present

User is affected if HarmonyOS version is exactly 5.0.0 and the 3D engine module with glTF model loading capability is in use on the device.
