The issue appears in all installations of these versions, regardless of operating system or deployment environment, because the flaw is located in the core file\u2011processing routine.", "description_and_impact": "This vulnerability is a NULL pointer dereference inside Adobe Substance3D Designer. When triggered, the application dereferences a null pointer and crashes, resulting in an immediate denial of service to anyone using that instance. The weakness is a classic null pointer error (CWE\u2011476) and threatens only the local application, not the underlying operating system or other network services.", "risk_and_exploitability": "The CVSS score of 5.5 places this as a medium severity issue, while the EPSS score of less than 1% indicates a very low likelihood of exploitation at this time. The vulnerability is not listed in CISA\u2019s KEV catalog. An attacker must first craft a malicious Designer file and convince a victim to open it; remote exploitation is not possible. Because the flaw requires user interaction, the risk is contained to environments where users download or receive Designer files from untrusted sources."}}}}, "created": "2026-02-11T21:52:04.461631+00:00", "updated": "2026-04-17T20:45:25.760132+00:00", "vendors": ["adobe", "adobe$PRODUCT$substance_3d_designer"]}
