CVE-2025-53012

This vulnerability is classified as Uncontrolled Resource Consumption (CWE-400), which allows attackers to cause denial of service by exhausting system resources. 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. Affected products include: Linuxfoundation Materialx. Version information: version 1.39.2.
