CVE-2026-47482
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 missing release of memory after effective lifetime. 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 has a memory leak vulnerability where memory is not properly released after its effective lifetime. An attacker can exploit this to cause memory exhaustion, leading to denial of service. The vulnerability stems from missing deallocation calls in specific code paths.

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 versionRun 'tritonserver --version' or check the Docker image tag if using containers. On Linux systems, also check via 'dpkg -l | grep triton' or 'pip show triton-inference-server' if installed via pip.Affected if The installed version falls within the vulnerable version range and has not been patched.
-
Confirm Linux environmentVerify the OS is Linux using 'uname -a' or 'cat /etc/os-release'. The CVE specifically affects the Linux platform.Affected if Running Triton Inference Server on Linux and the version is unpatched.
-
Monitor memory consumptionUse 'ps aux | grep tritonserver' to locate the process, then monitor its RSS memory with 'ps -o rss=' or via 'top' / 'htop' over time. Track memory growth trend over several hours under normal workload.Affected if Memory usage grows continuously without stabilization, indicating a memory leak.
-
Check for model loading activityReview Triton logs for model load/unload operations using 'cat /var/log/triton/*.log' or container logs via 'docker logs'. The vulnerability stems from missing deallocation in specific code paths related to model lifecycle.Affected if Frequent model loading/unloading operations are performed and memory usage increases with each cycle.
If running an unpatched version of Triton Inference Server on Linux with observable continuous memory growth during normal operation or model loading cycles, the environment is likely affected by this memory leak vulnerability.

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 vendor patch when available; in the interim, implement resource limits and monitor memory usage to mitigate DoS risk. Ensure proper memory management practices are followed in custom extensions or models.
