CVE-2025-33176 is a vulnerability identified in NVIDIA RunAI, a platform used for orchestrating AI workloads across various environments. The flaw stems from improper restriction of communication channels to intended endpoints (CWE-923), which means that the software does not adequately enforce that communications occur only between authorized parties. This can be exploited by an attacker with access to an adjacent network segment to interfere with or redirect communications. The attack requires the attacker to have low privileges on the system and to trick a user into interaction, making exploitation somewhat complex. Successful exploitation can lead to escalation of privileges, allowing the attacker to gain higher-level access than intended. Additionally, it can result in data tampering and information disclosure, impacting the confidentiality and integrity of data processed or managed by RunAI. The CVSS 3.1 base score is 6.2 (medium), reflecting the attack vector as adjacent network (AV:A), high attack complexity (AC:H), low privileges required (PR:L), user interaction required (UI:R), and scope changed (S:C). Confidentiality impact is low, integrity impact is high, and availability is not affected. No public exploits are known at this time, but the vulnerability is significant given the critical role of RunAI in AI infrastructure. The affected versions include all prior to 2.22.48, and no patch links were provided in the source, indicating that users should monitor NVIDIA advisories for updates. The vulnerability's presence in AI orchestration software raises concerns about the security of AI workloads and data integrity in environments relying on NVIDIA RunAI.

For European organizations, the impact of CVE-2025-33176 could be substantial, particularly for those heavily invested in AI research, development, and deployment using NVIDIA RunAI. Escalation of privileges could allow attackers to gain unauthorized control over AI orchestration environments, potentially leading to manipulation of AI workloads or theft of sensitive data. Data tampering could corrupt AI models or datasets, undermining the reliability and trustworthiness of AI outputs. Information disclosure risks could expose proprietary algorithms, training data, or personal data processed by AI systems, raising compliance issues under GDPR. The requirement for adjacent network access limits the attack surface but does not eliminate risk, especially in environments with shared or poorly segmented networks. The need for user interaction also reduces likelihood but social engineering or insider threats could facilitate exploitation. Overall, the vulnerability threatens confidentiality and integrity of AI infrastructure, which is critical for innovation and competitive advantage in Europe’s AI sector.

To mitigate CVE-2025-33176, European organizations should: 1) Immediately upgrade NVIDIA RunAI to version 2.22.48 or later once available, as this is the definitive fix for the vulnerability. 2) Implement strict network segmentation and access controls to restrict adjacent network access to RunAI components, minimizing exposure to potential attackers. 3) Employ strong user awareness training to reduce the risk of social engineering or inadvertent user interaction that could facilitate exploitation. 4) Monitor network traffic for anomalous communications involving RunAI endpoints, using intrusion detection/prevention systems tuned to detect lateral movement or unauthorized channel establishment. 5) Review and harden privilege management policies within RunAI environments to limit the impact of any potential escalation. 6) Maintain up-to-date inventories of affected software versions and conduct regular vulnerability assessments focused on AI orchestration infrastructure. 7) Coordinate with NVIDIA support and subscribe to security advisories for timely patch information and guidance.
