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 · unedited
NVIDIA TRT-LLM for any platform contains a deserialization vulnerability and unsafe serialized handle. A successful exploit of this vulnerability might lead to code execution, data tampering, and information disclosure.

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 confidence

NVIDIA TRT-LLM contains a deserialization vulnerability where unsafe handling of serialized data/handles allows attackers to potentially execute arbitrary code, tamper with data, or disclose sensitive information. The vulnerability stems from improper validation during deserialization of untrusted input.

MitigationApply vendor-provided patches when available; avoid deserializing data from untrusted sources and implement strict input validation on serialized handles. Consider migrating to safer serialization formats if possible.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify TensorRT LLM installation
    Run 'pip list | grep tensorrt' or check for the tensorrt_llm package in your Python environment
    Affected if tensorrt_llm is installed with version less than 1.2.0
  2. Determine installed TensorRT LLM version
    Run 'pip show tensorrt-llm' or 'python -c "import tensorrt_llm; print(tensorrt_llm.__version__)"' to get the exact version number
    Affected if The version reported is lower than 1.2.0 or the version cannot be determined (indicating an old release)
  3. Locate serialized model or engine files
    Search for .engine, .safetensors, or other serialized model files in your model directories - check paths like /models, ~/tensorrt_models, or custom model paths used in your inference pipelines
    Affected if Serialized model files exist and are loaded by the TensorRT LLM runtime
  4. Inspect deserialization code paths
    Review application code that loads TensorRT LLM models - look for functions like 'load_engine', 'from_serialized', 'deserialize', or model loading pipelines that accept file paths or serialized buffers
    Affected if Code loads serialized content from files, network sources, or user-controlled paths without validation

You are affected if TensorRT LLM version is below 1.2.0 AND your system loads or processes serialized model data, checkpoints, or engine files.

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.

Upgrade available Upgrade to 1.2 or later
Fixed in 1.2
Interim mitigation

Apply vendor-provided patches when available; avoid deserializing data from untrusted sources and implement strict input validation on serialized handles. Consider migrating to safer serialization formats if possible.

Recommended fix High confidence

TensorRT LLM version 1.2 or later

  1. 1. Identify the current installed version of TensorRT LLM by running `pip show tensorrt_llm` or checking your container image tag
  2. 2. If running TensorRT LLM version < 1.2, plan for upgrade to version 1.2 or later
  3. 3. Back up any serialized models, configurations, or custom plugins that may have been created with the vulnerable version
  4. 4. Upgrade TensorRT LLM by running `pip install --upgrade tensorrt_llm` or pulling the version 1.2+ container image
  5. 5. After upgrade, re-validate any serialized model files or handles before use to ensure compatibility with the patched version
  6. 6. Verify the upgrade was successful by confirming the installed version is >= 1.2
Caveat Serialization formats may differ between vulnerable and fixed versions; re-serialize any model handles or configs created with the old version before use
