{"cve":"CVE-2025-53012","nvd":{"published":"2025-08-01T18:15:54.990","modified":"2026-06-17T09:37:28.523","status":"Analyzed","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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","score":5.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400"],"references":["https://github.com/AcademySoftwareFoundation/MaterialX/blob/main/documents/Specification/MaterialX.Specification.md#mtlx-file-format-definition","https://github.com/AcademySoftwareFoundation/MaterialX/pull/2233/commits/6182c07467297416a30d148ab531d81198686dc5","https://github.com/AcademySoftwareFoundation/MaterialX/releases/tag/v1.39.3","https://github.com/AcademySoftwareFoundation/MaterialX/security/advisories/GHSA-qc2h-74x3-4v3w"],"products":["linuxfoundation:materialx"],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-53012","score":0.00892,"percentile":0.59445,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-qc2h-74x3-4v3w","url":"https://osv.dev/vulnerability/GHSA-qc2h-74x3-4v3w","summary":"MaterialX Lack of MTLX Import Depth Limit Leads to DoS (Denial-Of-Service) Via Stack Exhaustion","modified":"2026-07-07T17:57:07.457098879Z","packages":[{"ecosystem":"PyPI","name":"materialx","purl":"pkg:pypi/materialx","ranges":[">=1.39.2 <1.39.3"],"fixed":["1.39.3"]}]},{"id":"PYSEC-2026-1608","url":"https://osv.dev/vulnerability/PYSEC-2026-1608","summary":"MaterialX Lack of MTLX Import Depth Limit Leads to DoS (Denial-Of-Service) Via Stack Exhaustion","modified":"2026-07-07T17:47:03.417953871Z","packages":[{"ecosystem":"PyPI","name":"materialx","purl":"pkg:pypi/materialx","ranges":[">=1.39.2 <1.39.3"],"fixed":["1.39.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
