CVE-2025-33030 is a vulnerability identified in the firmware of certain Intel(R) Neural Processing Unit (NPU) drivers operating within the user-space (Ring 3). The flaw arises from improper condition checks in the firmware, which can be exploited by an authenticated but unprivileged local user to escalate privileges and cause data corruption. The attack vector requires local access and low complexity, with no need for user interaction or special internal knowledge, making it accessible to a broad range of potential attackers with legitimate user credentials. The vulnerability primarily impacts the integrity of the system by enabling data corruption, while confidentiality and availability remain unaffected. The CVSS 4.0 base score is 2.0, reflecting the low severity due to limited impact and the requirement for local authenticated access. There are no known exploits in the wild, and no patches have been publicly released at the time of this report. The vulnerability affects Intel NPU drivers, which are increasingly used in AI and machine learning workloads to accelerate processing. Given the growing deployment of NPUs in enterprise and cloud environments, this vulnerability could pose risks where local user access is granted. However, the lack of confidentiality and availability impact and the low complexity of exploitation limit the overall threat level. Organizations should monitor Intel advisories for patches and updates to address this issue.

For European organizations, the primary impact of CVE-2025-33030 is the potential for local unprivileged users to corrupt data processed or managed by Intel NPU drivers, which could affect the integrity of AI workloads or other computations relying on these processors. While confidentiality and availability are not impacted, data corruption could lead to erroneous outputs or system instability in critical AI-driven applications, potentially affecting decision-making processes or automated systems. Organizations with multi-user environments, such as research institutions, universities, or enterprises with shared workstations, are at higher risk if local user privileges are not tightly controlled. The vulnerability does not enable remote exploitation, limiting its impact on cloud or remote services unless local access is compromised. The absence of known exploits reduces immediate risk, but the increasing adoption of Intel NPUs in European technology sectors means that the vulnerability warrants attention to prevent future exploitation. Overall, the impact is low but non-negligible for environments relying heavily on Intel NPU hardware for AI or data processing tasks.

1. Monitor Intel's official security advisories and apply firmware and driver updates promptly once patches addressing CVE-2025-33030 are released. 2. Restrict local user privileges rigorously, ensuring that only trusted users have authenticated access to systems with Intel NPU drivers installed. 3. Implement strict access controls and user account management policies to minimize the number of users with local access rights. 4. Employ endpoint detection and response (EDR) solutions to monitor for unusual activity related to NPU driver usage or attempts to exploit privilege escalation. 5. Conduct regular integrity checks and validation of AI workload outputs to detect potential data corruption early. 6. Isolate critical AI processing systems from general user environments to reduce exposure to local attacks. 7. Educate system administrators and security teams about the specific risks associated with Intel NPU drivers and the importance of timely patching. 8. Consider implementing application whitelisting and restricting execution of unauthorized software that could attempt to exploit this vulnerability.
