Overview
CVE-2025-33211 is a high-severity vulnerability affecting NVIDIA Triton Server for Linux. This vulnerability stems from improper validation of specified quantity in input, potentially allowing an attacker to trigger a denial-of-service (DoS) condition. This article provides a comprehensive analysis of the vulnerability, including technical details, CVSS score breakdown, potential impact, and mitigation strategies.
Technical Details
The vulnerability resides in the handling of input quantities within NVIDIA Triton Server. Specifically, the server fails to adequately validate the specified quantity of certain input parameters. An attacker can exploit this flaw by crafting malicious input that bypasses the validation checks. This leads to a resource exhaustion scenario or unexpected server behavior, ultimately resulting in a denial-of-service.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of security vulnerabilities. CVE-2025-33211 has a CVSS score of 7.5, indicating a HIGH severity vulnerability. Here’s a breakdown:
- Base Score: 7.5
- Vector: Likely something like (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) – indicating Network attack vector, Low attack complexity, No privileges required, No User interaction, Unchanged scope, No Confidentiality impact, No Integrity impact, and High Availability impact. (This is an estimated vector based on the description).
- Explanation: This score reflects the ease with which an attacker can remotely trigger the DoS condition without requiring any user interaction or privileges. The high availability impact signifies the significant disruption caused by the DoS.
Possible Impact
A successful exploit of CVE-2025-33211 can have significant consequences:
- Denial of Service (DoS): The primary impact is the disruption of Triton Server’s availability. The server becomes unresponsive, preventing legitimate users and applications from accessing its services.
- Service Interruption: This can lead to service outages for applications relying on Triton Server for AI inference and other tasks.
- Reputational Damage: Prolonged outages can damage an organization’s reputation, particularly if the server supports critical business functions.
Mitigation and Patch Steps
NVIDIA has released a patch to address CVE-2025-33211. The recommended mitigation is to update your NVIDIA Triton Server installation to the latest version containing the fix. Follow these steps:
- Check Your Version: Determine the current version of NVIDIA Triton Server you are running.
- Apply the Patch: Download and install the latest patch from NVIDIA. Refer to the NVIDIA security advisory for specific instructions.
- Verify Installation: After applying the patch, verify that the vulnerability is resolved.
- Monitor Your Systems: Continuously monitor your Triton Server instances for any signs of suspicious activity.
Refer to NVIDIA’s official security advisory for the specific affected versions and remediation steps.
