CVE-2025-33192 is a firmware vulnerability identified in the NVIDIA DGX Spark GB10 platform, specifically within the SROOT firmware component. The root cause is an unchecked return value that leads to a NULL pointer dereference (CWE-690). This flaw allows an attacker with local access to trigger an arbitrary memory read, which can cause the system to crash, resulting in a denial of service (DoS). The vulnerability does not require any privileges (PR:N) or user interaction (UI:N), but the attack vector is local (AV:L), meaning the attacker must have local access to the device. The scope is classified as changed (S:C), indicating that the vulnerability affects components beyond the initially vulnerable code, potentially impacting the entire system. The confidentiality impact is limited (C:L) due to the arbitrary memory read, but integrity is not affected (I:N), and availability is impacted (A:L) due to the DoS condition. No patches are currently linked, but the vulnerability affects all versions prior to the OTA0 firmware update. No known exploits have been reported in the wild, suggesting limited active exploitation at this time. The DGX Spark platform is widely used in high-performance computing and AI workloads, making this vulnerability relevant for organizations relying on these systems for critical operations.

For European organizations, the primary impact of CVE-2025-33192 is operational disruption due to denial of service on NVIDIA DGX Spark systems. These systems are often deployed in AI research, data centers, and HPC environments, where availability is critical. An attacker with local access could cause system crashes, leading to downtime and potential delays in research or production workloads. The limited confidentiality impact means sensitive data exposure risk is low, but the arbitrary memory read could potentially be leveraged in more complex attack chains if combined with other vulnerabilities. Organizations relying heavily on DGX Spark for AI model training or data processing could face significant productivity losses. Additionally, the need for local access reduces the attack surface but does not eliminate risk from insider threats or compromised local accounts. The absence of known exploits provides a window for remediation but should not lead to complacency.

1. Apply the OTA0 firmware update from NVIDIA as soon as it becomes available to remediate the vulnerability. 2. Restrict physical and local access to DGX Spark systems to trusted personnel only, implementing strict access controls and monitoring. 3. Employ network segmentation to isolate DGX Spark devices from less trusted network zones, reducing the risk of unauthorized local access. 4. Monitor system logs and firmware behavior for unusual activity that could indicate exploitation attempts. 5. Implement endpoint security solutions capable of detecting anomalous local activities on DGX Spark systems. 6. Conduct regular security audits and penetration testing focusing on local access vectors to identify and mitigate potential attack paths. 7. Educate staff on the risks of insider threats and enforce policies to prevent unauthorized access to critical AI infrastructure.
