Overview
CVE-2025-33195 is a medium severity vulnerability identified in the SROOT firmware of NVIDIA DGX Spark GB10. This flaw allows a potential attacker to trigger unexpected memory buffer operations, which could lead to a variety of negative consequences. This article provides a comprehensive analysis of the vulnerability, its potential impact, and available mitigation strategies.
Technical Details
The vulnerability, CVE-2025-33195, resides within the SROOT firmware of the NVIDIA DGX Spark GB10. The specifics of the underlying cause relate to insufficient validation or handling of memory operations within the SROOT firmware. An attacker who can successfully exploit this weakness can manipulate the firmware’s memory handling. The exact attack vector and required privileges to exploit this vulnerability are not fully specified in public documentation at this time but require local access to the system.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of security vulnerabilities. CVE-2025-33195 has been assigned a CVSS score of 4.4, indicating a MEDIUM severity.
- CVSS Score: 4.4
- Vector String: (This is an example and would be determined by NIST upon final analysis. Example: AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:L)
- Severity: Medium
This score reflects the potential impact of the vulnerability when successfully exploited, balanced against the relative difficulty of exploitation. It is important to note that the CVSS score is only a guideline, and the actual risk posed by the vulnerability will vary depending on the specific environment and security controls in place.
Possible Impact
A successful exploit of CVE-2025-33195 could result in several adverse outcomes:
- Data Tampering: The attacker might be able to modify sensitive data stored within the affected memory regions.
- Denial of Service (DoS): By causing the system to crash or become unresponsive, the attacker could disrupt normal operations.
- Escalation of Privileges: In some scenarios, the vulnerability could be leveraged to gain elevated privileges on the system, enabling further malicious activities.
Mitigation or Patch Steps
The recommended mitigation strategy is to apply the security update provided by NVIDIA. Please refer to the NVIDIA security bulletin for specific instructions on how to download and install the update for your DGX Spark GB10 system. It is crucial to apply the update promptly to minimize the risk of exploitation.
Follow these steps:
- Visit the NVIDIA security bulletin (linked in the References section).
- Identify the appropriate update for your specific DGX Spark GB10 model.
- Download the update package.
- Carefully follow the installation instructions provided by NVIDIA.
- Verify the successful installation of the update.
- Consider network segmentation and access control to limit the potential attack surface.
