CVE-2025-53011

Linuxfoundation Materialx NULL pointer dereference

7.5 HIGHPublic exploitEPSS 0.54%
  1. Published1 Aug 2025

Description

MaterialX is an open standard for the exchange of rich material and look-development content across applications and renderers. In version 1.39.2, when parsing shader nodes in a MTLX file, the MaterialXCore code accesses a potentially null pointer, which can lead to crashes with maliciously crafted files. An attacker could intentionally crash a target program that uses MaterialX by sending a malicious MTLX file. This is fixed in version 1.39.3.
