Overview
CVE-2025-33196 is a medium severity vulnerability affecting NVIDIA DGX Spark GB10 systems. This vulnerability resides within the SROOT firmware and could allow an attacker to cause a resource to be reused, potentially leading to information disclosure. This article provides a detailed analysis of the vulnerability, its potential impact, and steps to mitigate the risk.
Technical Details
The vulnerability stems from an issue in the SROOT firmware of the NVIDIA DGX Spark GB10. An attacker can exploit this by triggering a scenario where a resource is improperly released or not properly deallocated, leading to its subsequent reuse in an insecure manner. This reuse can then allow the attacker to gain access to sensitive information that was previously stored in that resource. The specific mechanism to trigger this is not publicly detailed, but further investigation into the SROOT firmware’s resource management is likely required to understand the exploit vectors fully.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of security vulnerabilities. For CVE-2025-33196, the CVSS score is 4.4, indicating a MEDIUM severity.
- CVSS Score: 4.4
- Vector: (While the vector string isn’t provided, the score suggests a localized or physical attack is likely)
- Explanation: This score suggests that the exploit requires some level of access to the system and results in information disclosure. The impact is not considered critical, but it is still significant enough to warrant attention and mitigation.
Possible Impact
A successful exploit of CVE-2025-33196 could result in the following:
- Information Disclosure: Sensitive data stored within the reused resource could be exposed to the attacker. This may include configuration information, cryptographic keys, or other confidential data critical to the system’s operation.
- Compromised System Integrity: While the vulnerability is classified as information disclosure, further exploitation using the leaked information could potentially lead to further compromise of the system.
- Data Breach: Depending on the nature of the leaked information, the vulnerability could contribute to a larger data breach, impacting the confidentiality of data processed by the DGX Spark GB10 system.
Mitigation & Patch Steps
The primary mitigation for CVE-2025-33196 is to apply the security patch provided by NVIDIA. Follow these steps:
- Identify Affected Systems: Determine if your NVIDIA DGX Spark GB10 systems are running the vulnerable SROOT firmware version.
- Download the Patch: Obtain the security update from the NVIDIA Customer Support website. The exact location of the patch is detailed in the NVIDIA security bulletin linked in the references below.
- Apply the Patch: Follow NVIDIA’s instructions carefully to apply the patch. Ensure you back up your system before applying any updates.
- Verify the Installation: After patching, verify that the SROOT firmware has been updated to the corrected version.
- Monitor for Anomalies: Continuously monitor your systems for any suspicious activity after applying the patch.
