CVE-2025-53012

5.5 mediumEPSS 0.9%

Medium (5.5) in linuxfoundation materialx. EPSS 0.9% chance of exploitation in the next 30 days. Fixed in materialx 1.39.3.

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.
