CVE-2025-33230 is an OS command injection vulnerability classified under CWE-78, affecting the NVIDIA CUDA Toolkit, specifically the Nsight Systems installer for Linux. The vulnerability exists in the .run installer script, which improperly sanitizes or neutralizes special characters in the user-supplied installation path. This flaw allows an attacker with limited privileges to craft a malicious installation path containing shell metacharacters or commands that the installer executes unintentionally. Because the installer runs with elevated privileges during installation, the injected commands can execute with higher privileges than the attacker initially possesses. This can lead to privilege escalation, enabling the attacker to execute arbitrary code, tamper with data, cause denial of service by disrupting system or application functionality, or disclose sensitive information. The vulnerability affects all CUDA Toolkit versions prior to 13.1, which means any system running these versions is susceptible if the attacker can influence the installation path. Exploitation requires local access and some user interaction, such as initiating or approving the installation process. The CVSS v3.1 base score is 7.3, reflecting high severity due to the combination of high impact on confidentiality, integrity, and availability, and relatively low attack complexity. No public exploits have been reported yet, but the risk remains significant given the widespread use of CUDA in scientific computing, AI development, and other GPU-accelerated applications.

The impact of CVE-2025-33230 is substantial for organizations relying on NVIDIA CUDA Toolkit for GPU-accelerated computing, AI research, and development environments. Successful exploitation can lead to unauthorized privilege escalation, allowing attackers to gain control over affected systems. This can result in arbitrary code execution, potentially enabling attackers to deploy malware, manipulate critical data, or disrupt services. Data tampering and information disclosure could compromise intellectual property or sensitive research data. Denial of service conditions could interrupt critical computational workloads, affecting business continuity. Since the vulnerability requires local access and user interaction, insider threats or attackers who have gained limited access could leverage this flaw to escalate privileges and move laterally within networks. The broad use of CUDA in academia, research institutions, and industries such as automotive, healthcare, and finance increases the potential attack surface and impact severity.

To mitigate CVE-2025-33230, organizations should upgrade to NVIDIA CUDA Toolkit version 13.1 or later as soon as it becomes available, as this version addresses the vulnerability. Until the patch is applied, restrict access to systems where CUDA Toolkit is installed, especially limiting local user permissions to trusted personnel only. Avoid running the Nsight Systems installer with elevated privileges unless absolutely necessary and ensure that installation paths are validated and sanitized to prevent injection of malicious commands. Employ application whitelisting and endpoint protection solutions to detect and block suspicious installer behavior. Conduct user training to raise awareness about the risks of running untrusted installers or modifying installation paths. Additionally, monitor system logs for unusual activity during installation processes and implement strict access controls on development and research environments using CUDA. Regularly review and audit installed software versions to ensure timely patching of vulnerable components.
