CVE-2025-23276 is a high-severity vulnerability identified in the NVIDIA GPU Display Drivers, specifically affecting versions R535, R570, and R575 on Windows platforms. The vulnerability is categorized under CWE-552, which refers to files or directories being accessible to external parties, indicating improper access controls. The root cause lies within the NVIDIA Installer for Windows, where an attacker with limited privileges (local access) can exploit this flaw to escalate their privileges. The CVSS v3.1 score of 7.8 reflects a high impact, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Exploitation could lead to a range of severe consequences including privilege escalation, denial of service, arbitrary code execution, information disclosure, and data tampering. Although no known exploits are currently reported in the wild, the vulnerability's nature and impact make it a critical concern for affected systems. The vulnerability allows attackers who have already gained limited access to the system to leverage improperly protected files or directories to gain higher privileges or execute malicious code, potentially compromising the entire system. This could be particularly dangerous in environments where NVIDIA GPU drivers are widely deployed, such as workstations used for graphics-intensive applications, scientific computing, or AI workloads.

For European organizations, the impact of CVE-2025-23276 can be significant due to the widespread use of NVIDIA GPUs in various sectors including technology, research, finance, and manufacturing. Successful exploitation could lead to unauthorized access to sensitive data, disruption of critical services through denial of service, and potential manipulation or destruction of data integrity. Organizations relying on GPU-accelerated computing for AI, machine learning, or data analysis could face operational downtime and data breaches. The escalation of privileges could allow attackers to bypass security controls, move laterally within networks, and establish persistent footholds, increasing the risk of broader compromise. Given the high confidentiality, integrity, and availability impacts, this vulnerability poses a substantial risk to data protection compliance under regulations such as GDPR, potentially leading to legal and financial repercussions for European entities.

To mitigate the risks posed by CVE-2025-23276, European organizations should implement the following specific measures: 1) Immediately verify and apply any patches or updates released by NVIDIA for the affected driver versions R535, R570, and R575. If patches are not yet available, consider rolling back to earlier, unaffected versions where feasible. 2) Restrict local access to systems running vulnerable NVIDIA drivers by enforcing strict user privilege management and limiting administrative rights to essential personnel only. 3) Employ application whitelisting and endpoint protection solutions capable of detecting and preventing unauthorized modifications or executions related to the NVIDIA installer or driver files. 4) Monitor system logs and security events for unusual activities related to NVIDIA driver installation or modification processes, focusing on privilege escalation attempts. 5) Segment networks to isolate critical GPU-accelerated systems, reducing the risk of lateral movement if a compromise occurs. 6) Educate IT and security teams about this vulnerability to ensure rapid response and incident handling. 7) Conduct regular vulnerability assessments and penetration testing focusing on local privilege escalation vectors to identify and remediate similar weaknesses proactively.
