CVE-2025-6633 is a high-severity vulnerability classified as CWE-787 (Out-of-Bounds Write) affecting Autodesk 3ds Max version 2026. The vulnerability arises when the software parses a maliciously crafted RBG file, which can trigger an out-of-bounds write condition. This type of vulnerability occurs when a program writes data outside the boundaries of allocated memory, potentially overwriting adjacent memory regions. Exploiting this flaw can lead to several adverse outcomes, including application crashes, data corruption, or arbitrary code execution within the context of the 3ds Max process. The CVSS v3.1 base score is 8.3, indicating a high level of severity. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:L) reveals that the attack can be performed remotely over the network without privileges but requires user interaction (e.g., opening or importing the malicious RBG file). The vulnerability affects confidentiality and integrity at a high level and availability to a lesser extent. No known exploits are currently reported in the wild, and no patches have been linked yet. Given the nature of 3ds Max as a widely used 3D modeling and animation tool in industries such as media, entertainment, and design, this vulnerability poses a significant risk if weaponized, especially in environments where untrusted files might be imported or shared.

For European organizations, particularly those in creative industries, media production, architecture, and engineering sectors that rely heavily on Autodesk 3ds Max, this vulnerability could have serious consequences. Successful exploitation could lead to unauthorized code execution, allowing attackers to compromise sensitive intellectual property, disrupt production workflows, or gain footholds within corporate networks. The high confidentiality and integrity impact means that proprietary designs or client data could be exposed or altered. Even a denial-of-service condition caused by crashes could result in costly downtime. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to deliver malicious RBG files. This risk is amplified in collaborative environments where files are frequently exchanged. Additionally, compromised systems could be used as pivot points for broader network intrusions, increasing the overall threat to organizational cybersecurity posture in Europe.

Organizations should implement a multi-layered mitigation approach: 1) Restrict the import of RBG files from untrusted or external sources and enforce strict file validation policies. 2) Educate users on the risks of opening files from unknown origins and implement security awareness training focused on social engineering tactics. 3) Monitor network traffic and endpoint behavior for anomalies related to 3ds Max processes, including unexpected crashes or memory corruption indicators. 4) Employ application whitelisting and sandboxing techniques to limit the impact of potential exploitation. 5) Maintain up-to-date backups of critical project files to enable recovery from data corruption. 6) Autodesk should be engaged to obtain patches or updates as soon as they become available, and organizations should prioritize timely deployment. 7) Use endpoint detection and response (EDR) tools capable of detecting exploitation attempts related to out-of-bounds memory writes. 8) Consider network segmentation to isolate systems running 3ds Max from sensitive parts of the corporate network to limit lateral movement if compromise occurs.
