CVE-2025-45332Network attack vector

Renderer crash via premature material property assignment

Published Jun 25, 2025 · Updated Jun 25, 2025

Null pointer dereference in vkoskiv c-ray 1.1 allows remote attackers to crash the renderer via a crafted Wavefront material file. The parse_mtllib function leaves current as NULL until a material is created, then writes current->IOR when an Ni directive appears first. Processing an attacker-controlled material file is required, and the resulting dereference terminates the rendering process.
