{"id":"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.","aliases":["GHSA-7qw8-3vmf-gj32","PYSEC-2026-1607"],"modified":"2026-08-12T03:51:38.366295531Z","published":"2025-08-01T17:58:47.388Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-476"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/53xxx/CVE-2025-53011.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/academysoftwarefoundation/materialx","events":[{"introduced":"c27914b8d0ed042948ee40526458f2673f5284fa"},{"fixed":"3b79bd735036dc96942836a9d076b6af3bd8fbdf"}],"database_specific":{"extracted_events":[{"introduced":"1.39.2"},{"fixed":"1.39.3"}],"source":"AFFECTED_FIELD"}}],"versions":["1.39.2-NA","v1.39.3-rc1","v1.39.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-53011.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P"}]}
