CVE-2025-57109Network attack vector

Memory disclosure and interruption via freed mesh access

Published Oct 30, 2025 · Updated Oct 30, 2025

Heap use-after-free in Kitware VTK 9.5.0 allows remote attackers to access freed heap data or interrupt applications via malformed GLTF files. vtkGLTFImporter::ImportActors follows invalid scene-node references and reads string members from mesh objects already freed during actor import. The vulnerable path is reached when an application imports the crafted asset; published evidence establishes memory disclosure and service interruption, not code execution.
