Overview
CVE-2025-33197 describes a medium severity vulnerability affecting NVIDIA DGX Spark GB10 systems. The vulnerability resides in the SROOT firmware and is classified as a NULL pointer dereference. Successful exploitation of this vulnerability can lead to a denial of service (DoS) condition.
Technical Details
The vulnerability stems from a flaw in how the SROOT firmware handles certain input or operations. An attacker can trigger a condition that causes the firmware to attempt to access a memory address that has a NULL value. This NULL pointer dereference results in the system crashing or becoming unresponsive, leading to a denial of service. Further specifics of the triggering input or operations are detailed in NVIDIA’s security advisory.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-33197 is 4.3 (MEDIUM). The CVSS vector string isn’t available in the provided data, however the following parameters likely contribute to this score:
- Attack Vector (AV): Likely Network or Local, depending on the attack surface of the SROOT firmware.
- Attack Complexity (AC): Possibly High, requiring specific knowledge of the system and firmware internals to exploit.
- Privileges Required (PR): Likely High or Low, again depending on attack surface.
- User Interaction (UI): None or Required, depending on triggering actions.
- Scope (S): Changed or Unchanged.
- Confidentiality Impact (C): None
- Integrity Impact (I): None
- Availability Impact (A): High
Possible Impact
The primary impact of successfully exploiting CVE-2025-33197 is a denial of service. This means that the affected NVIDIA DGX Spark GB10 system may become unavailable, disrupting critical workloads, computations, or services it provides. This could result in downtime, data loss, or financial repercussions, depending on the system’s role within an organization.
Mitigation or Patch Steps
To mitigate the risk posed by CVE-2025-33197, it is crucial to apply the security patch or update provided by NVIDIA as soon as possible. Follow these steps:
- Visit the NVIDIA Product Security page (see references below) to download the relevant patch for your DGX Spark GB10 system.
- Carefully review the installation instructions provided by NVIDIA.
- Back up your system before applying any updates.
- Apply the patch according to NVIDIA’s recommendations.
- Verify that the patch has been successfully applied and that the system is functioning correctly.
If a patch is not immediately available, consider implementing temporary workarounds or security measures, if any are suggested by NVIDIA, to reduce the attack surface and minimize the risk of exploitation.
