{"id":"CVE-2025-53011","aliases":["GHSA-7qw8-3vmf-gj32","PYSEC-2026-1607"],"url":"https://o3.security/vulnerability/CVE-2025-53011","summary":"MaterialX is Vulnerable to NULL Pointer Dereference due to Unchecked implGraphOutput","details":"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.","published":"2025-08-01T17:58:47.388Z","modified":"2026-07-15T01:49:00.441083537Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"materialx","fixedVersion":"1.39.3"}],"fix":{"url":"https://github.com/AcademySoftwareFoundation/MaterialX/commit/7ac1c71de5187dc29793292b5a8dc6d784192ecf","label":"AcademySoftwareFoundation/MaterialX@7ac1c71"},"references":[{"type":"WEB","url":"https://github.com/AcademySoftwareFoundation/MaterialX/releases/tag/v1.39.3"},{"type":"WEB","url":"https://github.com/ShielderSec/poc/tree/main/CVE-2025-53011"},{"type":"ADVISORY","url":"https://github.com/AcademySoftwareFoundation/MaterialX/security/advisories/GHSA-7qw8-3vmf-gj32"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/53xxx/CVE-2025-53011.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-53011"},{"type":"FIX","url":"https://github.com/AcademySoftwareFoundation/MaterialX/commit/7ac1c71de5187dc29793292b5a8dc6d784192ecf"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:00.441083537Z"}}
