CVE-2025-33192 identifies a vulnerability in the SROOT firmware component of NVIDIA DGX Spark GB10 systems. The root cause is an unchecked return value that leads to a NULL pointer dereference, classified under CWE-690. This flaw allows an attacker with local access to the device to perform arbitrary memory reads, which can destabilize the system and cause denial of service conditions. The vulnerability affects all versions of the DGX Spark prior to the OTA0 firmware update. The CVSS v3.1 score of 5.7 indicates a medium severity, with an attack vector of local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality is low due to limited arbitrary memory read capabilities, integrity is not impacted, but availability can be disrupted due to system crashes or instability. There are no known exploits in the wild, and no patch links are currently available, indicating that mitigation relies on forthcoming firmware updates. This vulnerability is particularly relevant for organizations using NVIDIA DGX Spark systems in AI and high-performance computing environments, where uptime and data integrity are critical.

For European organizations, especially those involved in AI research, data science, and HPC, exploitation of this vulnerability could lead to denial of service on critical NVIDIA DGX Spark systems. This could disrupt computational workloads, delay research projects, and impact service availability. Although the confidentiality impact is limited, the arbitrary memory read capability could potentially be leveraged for further attacks if combined with other vulnerabilities. The requirement for local access reduces the risk of remote exploitation but highlights the importance of physical and network access controls. Organizations relying heavily on DGX Spark infrastructure for AI model training or data processing may experience operational downtime, affecting business continuity and competitive advantage. Additionally, sectors such as automotive, finance, and healthcare using AI workloads on these platforms could face compliance and regulatory challenges if service disruptions occur.

1. Apply the OTA0 firmware update from NVIDIA as soon as it becomes available to address the vulnerability. 2. Restrict physical and network access to NVIDIA DGX Spark systems to trusted personnel only, minimizing the risk of local exploitation. 3. Implement strict access controls and monitoring on management interfaces and local consoles of DGX Spark devices. 4. Use network segmentation to isolate DGX Spark systems from less secure network zones. 5. Regularly audit and review firmware versions and device configurations to ensure compliance with security best practices. 6. Employ intrusion detection systems to monitor for unusual local access attempts or system crashes indicative of exploitation attempts. 7. Develop incident response plans specifically for HPC and AI infrastructure to quickly address potential denial of service events. 8. Coordinate with NVIDIA support for timely updates and advisories related to DGX Spark vulnerabilities.
