CVE-2026-47478
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 Linux contains a vulnerability where an attacker can cause the use of an expired file descriptor. A successful exploit of this vulnerability might 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 Inference Server for Linux contains a vulnerability where an attacker can cause the use of an expired file descriptor. This file descriptor handling issue can lead to denial of service when the server attempts to use a file descriptor that has been closed or expired.

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 installationCheck if NVIDIA Triton Inference Server is installed by searching for the server binary or service. Common locations include /opt/tritonserver, /usr/local/bin/tritonserver, or use 'which tritonserver' or 'systemctl list-units | grep triton'Affected if Triton Inference Server is not installed on the system
-
Identify installed Triton versionRun 'tritonserver --version' or check the version via the package manager (e.g., 'dpkg -l | grep triton' or 'rpm -qa | grep triton')Affected if Unable to determine version or version is older than the patched release (compare against NVIDIA security bulletins)
-
Verify server is actively runningCheck if the Triton server process is running using 'ps aux | grep tritonserver' or 'systemctl status triton-server'Affected if Server is not running (the vulnerability requires an active server to be exploitable)
-
Monitor for denial of service indicatorsReview server logs in the designated log directory (typically under /var/log/tritonserver or the directory specified at startup) for errors related to file descriptors, closed handles, or unexpected crashesAffected if Logs show repeated file descriptor errors, crashes, or failure to access resources that indicate file descriptor mishandling
The environment is affected if NVIDIA Triton Inference Server for Linux is running and the installed version matches the vulnerable release prior to the security patch.

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.
From vendor dataApply the NVIDIA security patch when available. Until then, monitor for anomalous behavior and restrict access to trusted users only to reduce attack surface.
