CVE-2025-23327
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 Inference Server for Windows and Linux contains a vulnerability where an attacker could cause an integer overflow through specially crafted inputs. A successful exploit of this vulnerability might lead to denial of service and data tampering.
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 Inference Server contains an integer overflow vulnerability in its input processing that can be triggered by specially crafted inputs. Successful exploitation allows an attacker to potentially cause denial of service or manipulate data through the overflow condition.

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.
-
Confirm Triton Inference Server installationIdentify if NVIDIA Triton Inference Server is present in the environment by checking for the Triton container image or binary (e.g., 'tritonserver' process or 'nvcr.io/nvidia/tritonserver' image)Affected if Triton Inference Server is not installed or not running
-
Retrieve installed Triton versionCheck the Triton server version by querying the server's metadata endpoint (typically GET /v2/health/ready or inspect the container image tag/label)Affected if The version returned is < 25.05 (any version before 25.05)
-
Verify input processing is exposedConfirm the Triton inference endpoint is accessible and able to receive inference requests (check if network listener or HTTP/gRPC port is active)Affected if The server is running and accepting external or internal inference requests
-
Check network exposureReview network configuration to determine if Triton inference ports (usually 8000 for HTTP, 8001 for gRPC) are exposed to untrusted network segmentsAffected if The inference endpoints are accessible from untrusted network paths
The environment is affected if NVIDIA Triton Inference Server is running with any version prior to 25.05 and the server is accessible to process inference requests.

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 · scoped25.05
Restrict network access to Triton Inference Server endpoints, implement strict input validation and bounds checking on all inference request parameters, and apply vendor patches when available.
Triton Inference Server 25.05
- Upgrade Triton Inference Server to version 25.05 or later to remediate the integer overflow vulnerability
- For Linux systems, download and install the updated Triton Inference Server package from NVIDIA's official repository or download page
- For Windows systems, obtain and install the updated Triton Inference Server package from NVIDIA's official repository or download page
- After upgrading, verify the installation by checking the Triton Inference Server version to confirm the fix is applied
- Restart the Triton Inference Server service to ensure the updated version is fully operational
- Test that inference workloads function normally post-upgrade to ensure no regressions were introduced
