CVE-2025-53012 Information

Aug 02, 2025 cve

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 nested imports of MaterialX files can lead to a crash via stack memory exhaustion due to the lack of a limit on the \import chain\ depth. When parsing file imports recursion is used to process nested files; however there is no limit imposed to the depth of files that can be parsed by the library. By building a sufficiently deep chain of MaterialX files one referencing the next it is possible to crash the process using the MaterialX library via stack exhaustion. This is fixed in version 1.39.3.
