Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 1.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2026-0659, published on 2026-02-04, is an Out-of-Bounds Write vulnerability (CWE-787) with a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). It affects Autodesk Arnold and Autodesk 3ds Max when a maliciously crafted USD file is loaded or imported, forcing an out-of-bounds write condition.
A local attacker with no privileges can exploit this vulnerability by tricking a user into loading or importing the malicious USD file into the affected software. Successful exploitation enables the attacker to execute arbitrary code in the context of the current process, potentially leading to high-impact compromise of confidentiality, integrity, and availability.
