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 when software fails to adequately validate memory operations, allowing an attacker to perform out-of-bounds reads or writes. In this case, the flaw could enable an attacker with low-level privileges and local access to cause unexpected memory buffer operations, potentially leading to data tampering, denial of service (DoS), or escalation of privileges. 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 with an attack vector limited to local access (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), limited integrity impact (I:L), and limited availability impact (A:L). No known exploits have been reported in the wild, indicating that active exploitation is not currently observed. The DGX Spark platform is used primarily in high-performance computing and AI workloads, making the integrity and availability of these systems critical. The vulnerability's exploitation could disrupt operations or allow attackers to manipulate data or escalate privileges within the system, potentially compromising the security posture of affected environments.

For European organizations, particularly those engaged in AI research, scientific computing, or data-intensive workloads relying on NVIDIA DGX Spark systems, this vulnerability poses risks to data integrity and system availability. Exploitation could lead to unauthorized modification of data, disruption of critical computational tasks, or unauthorized privilege escalation, which may result in operational downtime or compromised research outputs. Given the local access requirement, insider threats or attackers who have gained initial footholds could leverage this vulnerability to deepen their access or disrupt services. The medium severity suggests that while the threat is not critical, it can still cause meaningful harm if left unaddressed. Organizations with high-value AI workloads or sensitive data processed on DGX Spark systems should prioritize mitigation to maintain trustworthiness and continuity of their computational environments.

1. Apply the OTA0 firmware update from NVIDIA as soon as it becomes available to remediate the vulnerability. 2. Restrict physical and local access to DGX Spark systems to trusted personnel only, minimizing the risk of local exploitation. 3. Implement strict access controls and monitoring on systems running DGX Spark to detect and prevent unauthorized local activity. 4. Employ host-based intrusion detection systems (HIDS) to monitor for anomalous memory operations or privilege escalation attempts. 5. Conduct regular audits of user privileges and system logs to identify potential misuse or early signs of exploitation. 6. Segregate DGX Spark systems within secure network segments to limit lateral movement in case of compromise. 7. Educate system administrators and users about the risks associated with local access vulnerabilities and enforce strong operational security practices.
