CVE-2025-33211
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNVIDIA Triton Server for Linux contains a vulnerability where an attacker may cause an improper validation of specified quantity in input. A successful exploit of this vulnerability may lead to denial of service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceNVIDIA Triton Server for Linux contains an input validation flaw where the server fails to properly validate a specified quantity in incoming requests. An attacker can send specially crafted requests with malformed quantity parameters to trigger the validation failure, causing the service to become unavailable.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Triton Inference Server installationCheck for Triton Server binaries or containers on the system. Common paths include /opt/tritonserver, /usr/local/bin/tritonserver, or look for docker containers named 'triton' or 'tritonserver'. Use commands: 'which tritonserver' or 'docker ps -a | grep -i triton'Affected if Triton Server is not found on the system (not affected)
-
Determine installed Triton Server versionRun 'tritonserver --version' or check the version of the Triton container image with 'docker images | grep triton'. Compare the version number against 25.10Affected if Version is below 25.10 (e.g., 25.09, 25.08, 24.xx, etc.)
-
Verify network exposure of Triton endpointsCheck if Triton Server HTTP/gRPC ports (typically 8000 for HTTP, 8001 for gRPC) are listening on external interfaces. Use 'netstat -tlnp | grep -E "8000|8001"' or 'ss -tlnp | grep -E "8000|8001"' to see listening addressesAffected if Service is listening on 0.0.0.0 or external IP addresses (not localhost only)
-
Confirm service is reachable via HTTP/REST APIAttempt a curl request to the Triton health endpoint: 'curl -s http://<server>:8000/v2/health/ping' where <server> is the Triton host. If the service responds, it is network accessibleAffected if HTTP endpoint responds to requests from external hosts
You are affected if Triton Inference Server version is below 25.10 AND the service is exposed to the network, as an attacker could send malformed quantity parameters to cause DoS.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped25.10
Apply NVIDIA's patched version of Triton Server when available; in the interim, restrict network access to the Triton Server endpoint and implement request rate limiting to reduce exploitability.
25.10
- 1. Back up current Triton Inference Server configuration and data
- 2. Stop the Triton Inference Server service
- 3. Upgrade Triton Inference Server to version 25.10 or later
- 4. Verify the new version is running: `tritonserver --version`
- 5. Restart the Triton Inference Server service
- 6. Test that inference requests are processing correctly
