Overview
CVE-2025-33198 is a reported vulnerability affecting NVIDIA DGX Spark GB10 systems. Specifically, the issue resides in the SROOT firmware. The nature of the vulnerability involves resource reuse, which, if successfully exploited, could lead to information disclosure.
This is a low severity vulnerability, according to the National Vulnerability Database (NVD) and NVIDIA’s own assessment.
Technical Details
The vulnerability stems from improper handling of resources within the SROOT firmware of the NVIDIA DGX Spark GB10. An attacker could potentially manipulate the system to reuse a resource in an unintended context. This improper reuse can expose sensitive information that was previously stored in the resource, leading to information disclosure. The specific attack vectors and prerequisites for exploitation are not publicly available at this time, but understanding the firmware’s resource management is critical for assessing the risk.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of vulnerabilities. For CVE-2025-33198, the CVSS score is 3.3, indicating a Low severity.
- CVSS Score: 3.3
- Vector String: (Not publicly available, consult NVD for full details when available)
- Severity: Low
A low CVSS score typically suggests that the vulnerability is difficult to exploit, requires specific preconditions, or has limited impact on the system.
Possible Impact
While classified as low severity, the potential impact of CVE-2025-33198 should not be entirely dismissed. Successful exploitation could result in information disclosure. The information disclosed could potentially be used for further attacks, although the low severity score suggests this is unlikely without further vulnerabilities being chained together.
The specific type of information that could be disclosed depends on the function of the reused resource and the data it previously contained. This could include configuration details, potentially sensitive data used by the SROOT firmware, or other information relevant to the system’s operation.
Mitigation or Patch Steps
The recommended mitigation is to apply the security updates provided by NVIDIA. Regularly check NVIDIA’s security bulletins and driver updates for your DGX Spark GB10 systems. Follow these steps:
- Visit the NVIDIA Product Security page (see References below).
- Identify the appropriate security bulletin or driver update that addresses CVE-2025-33198.
- Download and install the update according to NVIDIA’s instructions.
- Verify the installation to ensure the vulnerability is remediated.
In addition to patching, consider implementing security best practices, such as limiting network access to the DGX system, regularly auditing system logs, and employing intrusion detection systems to monitor for suspicious activity. Even for low severity vulnerabilities, a layered security approach can minimize the risk.
