Vulnerability

OOM via Huge Tensor Metadata and Circular Reference DoS in TFLite (.tflite) files

Files

  • poc_oom_tensor.tflite โ€” 256 bytes, flatbuffer claiming 4GB buffer allocation
  • poc_circular_refs.tflite โ€” 4KB, cross-referencing flatbuffer offsets causing parsing loops
  • benign.tflite โ€” Clean TFLite file for comparison

Reproduce

import tensorflow as tf
interpreter = tf.lite.Interpreter(model_path='poc_oom_tensor.tflite')  # OOM
