CVE-2025-33195 identifies a vulnerability in the SROOT firmware component of NVIDIA DGX Spark GB10 systems, specifically related to improper restriction of operations within the bounds of a memory buffer (CWE-119). This type of vulnerability typically arises from insufficient validation of memory operations, allowing an attacker to perform out-of-bounds reads or writes. In this case, the flaw could be exploited by an attacker with local access and low privileges to cause unexpected memory buffer operations. The consequences of exploitation include data tampering, denial of service (DoS), or escalation of privileges, potentially enabling the attacker to gain higher system control or disrupt system availability. The vulnerability affects all versions of the DGX Spark prior to the OTA0 firmware update. The CVSS 3.1 base score is 4.4, reflecting a medium severity level, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), no confidentiality impact (C:N), low integrity impact (I:L), and low availability impact (A:L). No known exploits have been reported in the wild, suggesting limited current exploitation but a potential risk if attackers develop techniques to leverage this flaw. The vulnerability was reserved in April 2025 and published in November 2025, indicating a recent discovery. Given the specialized nature of NVIDIA DGX Spark systems, typically used in AI and high-performance computing environments, the attack surface is limited to organizations deploying these systems. However, the impact on integrity and availability could be significant in critical AI workloads or research environments. The lack of available patches at the time of publication underscores the importance of monitoring vendor advisories and applying updates promptly once released.

For European organizations, particularly those engaged in AI research, data science, and high-performance computing, this vulnerability poses a risk to the integrity and availability of critical computational workloads. Exploitation could lead to unauthorized modification of data processed by DGX Spark systems, disruption of AI model training or inference tasks through denial of service, or unauthorized privilege escalation potentially enabling further compromise of the host environment. While confidentiality impact is not indicated, the integrity and availability risks could undermine trust in computational results and cause operational downtime. Organizations relying on NVIDIA DGX Spark for sensitive or mission-critical tasks may face operational delays and potential reputational damage if this vulnerability is exploited. The requirement for local access and low privileges reduces the risk from remote attackers but elevates the importance of internal security controls, including access management and monitoring. The absence of known exploits currently limits immediate threat but does not preclude future exploitation attempts, especially as threat actors increasingly target AI infrastructure. Given the strategic importance of AI and HPC in European technological development, the vulnerability could have broader implications if exploited at scale.

European organizations using NVIDIA DGX Spark systems should implement the following specific mitigations: 1) Restrict physical and local access to DGX Spark hardware to trusted personnel only, enforcing strict access controls and monitoring. 2) Employ robust privilege management to minimize the number of users with local low-level access, reducing the attack surface. 3) Monitor system logs and firmware behavior for anomalies indicative of memory corruption or unexpected operations. 4) Engage with NVIDIA to obtain and apply the OTA0 firmware update as soon as it becomes available to remediate the vulnerability. 5) Implement network segmentation to isolate DGX Spark systems from less trusted network zones, limiting lateral movement in case of compromise. 6) Conduct regular security audits and firmware integrity checks to detect unauthorized modifications. 7) Educate system administrators about the risks of local privilege escalation and the importance of timely patching. 8) Consider deploying host-based intrusion detection systems (HIDS) tailored to detect unusual firmware or memory behavior on DGX Spark systems. These measures go beyond generic advice by focusing on the unique operational context of DGX Spark environments and the specific nature of the vulnerability.
