Minimal Repro: TensorRT OnnxParserRefitter heap corruption
This folder is self-contained except for the TensorRT/ONNX Python environment.
It includes a clean baseline ONNX model, a clean STRIP_PLAN + REFIT TensorRT
engine, the malicious ONNX refit artifact, and a repro script.
Run from this folder:
python3 repro_memory_corruption.py
Expected: the child process calling OnnxParserRefitter.refit_from_file()
aborts with double free or corruption (out).
Primary artifact:
raw_7_floats_refit.onnx- Tensor name:
refit_weight - Declared dtype: FLOAT
- Declared shape:
[2, 3] - Expected raw bytes: 24
- Actual raw bytes: 28
