Overview
CVE-2025-33194 describes a medium-severity vulnerability found in the SROOT firmware of NVIDIA DGX Spark GB10 systems. This vulnerability arises from improper processing of input data, which could be exploited by an attacker to potentially disclose sensitive information or trigger a denial-of-service (DoS) condition. This article provides a detailed analysis of the vulnerability, its potential impact, and the necessary steps for mitigation.
Technical Details
The vulnerability resides within the SROOT firmware of the NVIDIA DGX Spark GB10. The specific flaw stems from the firmware’s handling of certain input data structures. An attacker could craft malicious input that triggers an out-of-bounds read or write, or leads to other memory corruption issues within the firmware. This could allow the attacker to read sensitive information residing in memory, or to disrupt the normal operation of the device, leading to a denial-of-service condition. The precise mechanism for exploiting this vulnerability will likely depend on the specific implementation details of the SROOT firmware and the targeted data processing routines.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns CVE-2025-33194 a score of 5.7, indicating a MEDIUM severity. This score reflects the potential for information disclosure or denial of service, combined with moderate attack complexity. The vector string associated with this score likely incorporates factors such as attack vector, attack complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact.
Possible Impact
A successful exploit of CVE-2025-33194 can have significant consequences:
- Information Disclosure: Attackers could potentially gain access to sensitive data stored within the DGX Spark GB10’s memory, potentially compromising confidential information.
- Denial of Service (DoS): Malicious input can crash the device or render it unresponsive, disrupting critical workloads.
The impact will vary depending on the system’s role and the sensitivity of the data it processes.
Mitigation or Patch Steps
To address CVE-2025-33194, NVIDIA has released a security update. Users of NVIDIA DGX Spark GB10 systems are strongly advised to:
- Apply the Security Update: Update the SROOT firmware to the latest version provided by NVIDIA. Refer to the NVIDIA security bulletin (linked below) for instructions on how to obtain and install the update.
- Follow Security Best Practices: Implement standard security practices, such as network segmentation and access control, to limit the potential impact of a successful exploit.
