Overview
CVE-2025-33187 is a critical vulnerability affecting NVIDIA DGX Spark GB10 systems. This flaw resides within the SROOT component and could allow an attacker with privileged access to bypass security measures and gain unauthorized access to protected areas of the System on a Chip (SoC).
Technical Details
The vulnerability in SROOT allows an attacker with sufficient privileges to potentially manipulate or access sensitive data within the SoC’s protected regions. This could be achieved through crafted requests or exploitation of insecure access control mechanisms. The specific attack vector and required prerequisites are detailed in NVIDIA’s advisory. Understanding the intricacies of SROOT’s operation within the DGX Spark GB10 architecture is key to comprehending the full scope of this vulnerability.
CVSS Analysis
This vulnerability has been assigned a CVSS score of 9.3, indicating its critical severity. This high score reflects the potential for significant impact, including code execution, information disclosure, data tampering, denial of service, and escalation of privileges. A successful exploit could compromise the entire system.
Possible Impact
The impact of CVE-2025-33187 is severe. A successful exploit could lead to:
- Code Execution: An attacker could execute arbitrary code on the system.
- Information Disclosure: Sensitive data stored within the protected areas of the SoC could be exposed.
- Data Tampering: Data integrity could be compromised, leading to corrupted data and system instability.
- Denial of Service: The system could be rendered unusable.
- Escalation of Privileges: An attacker could gain elevated privileges, allowing them to take complete control of the system.
