Detailsinfo

A vulnerability, which was classified as problematic, has been found in MaterialX (version now known). This issue affects the function implGraphOutput of the component MaterialXCore Shader Generation. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. The summary by CVE is:

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.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2025-53011 since 06/24/2025. The exploitation is known to be easy. The attack may be initiated remotely.
