CVE-2025-23284 is a high-severity vulnerability identified in NVIDIA's Virtual GPU (vGPU) software, specifically within the Virtual GPU Manager component of the GPU Display Drivers (version R570). The vulnerability is classified as a stack-based buffer overflow (CWE-121), which occurs when a malicious guest operating within a virtualized environment can exploit improper bounds checking to overwrite the stack memory. This flaw can lead to multiple severe consequences including arbitrary code execution, denial of service (DoS), information disclosure, and data tampering. The vulnerability requires local access with low privileges (PR:L) but does not require user interaction (UI:N). The attack vector is local (AV:L), meaning the attacker must have some level of access to the host or guest system to exploit the flaw. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability. Successful exploitation could allow an attacker to escalate privileges or disrupt GPU operations, potentially affecting the stability and security of virtualized environments that rely on NVIDIA vGPU technology. The vulnerability was reserved in January 2025 and published in August 2025, with no known exploits in the wild at the time of reporting. No official patches have been linked yet, indicating that affected organizations should prioritize monitoring and mitigation efforts.

For European organizations, the impact of CVE-2025-23284 is significant, especially for those utilizing NVIDIA vGPU technology in virtualized data centers, cloud services, or high-performance computing environments. Exploitation could lead to unauthorized code execution within virtual machines, compromising sensitive data and potentially allowing lateral movement within networks. This could disrupt critical services, cause data breaches, or lead to denial of service conditions affecting business continuity. Industries such as finance, healthcare, telecommunications, and government agencies that rely on GPU-accelerated virtualization for AI workloads, simulations, or graphical processing are particularly at risk. The vulnerability's local attack vector means that insider threats or compromised guest systems could be leveraged to exploit this flaw. Given the high confidentiality, integrity, and availability impacts, organizations could face regulatory repercussions under GDPR if personal data is exposed or systems are disrupted.

1. Immediate mitigation should include restricting access to virtualized environments running NVIDIA vGPU software to trusted and authenticated users only, minimizing the risk of local exploitation. 2. Implement strict network segmentation and monitoring to detect anomalous behavior within virtual machines and the host system. 3. Employ host-based intrusion detection systems (HIDS) and endpoint detection and response (EDR) solutions to identify potential exploitation attempts. 4. Regularly audit and harden virtualization infrastructure configurations to reduce attack surface, including disabling unnecessary services and enforcing least privilege principles. 5. Monitor NVIDIA's official channels for patches or updates addressing CVE-2025-23284 and plan for rapid deployment once available. 6. Consider temporary mitigation strategies such as disabling or limiting vGPU usage in non-critical environments until patches are applied. 7. Conduct security awareness training for administrators and users on the risks associated with local privilege escalation vulnerabilities in virtualized environments.
