TFLite Tile Kernel RCE PoC

Integer overflow in TFLite Tile kernel (tile.cc:51) → heap buffer overflow with attacker-controlled data → RCE.

Files

• tile_rce_precise.tflite — 492-byte PoC model (valid TFL3 FlatBuffer)
• build_tile_rce.py — Generator script

Reproduce

import tensorflow as tf
interpreter = tf.lite.Interpreter(model_path="tile_rce_precise.tflite")
interpreter.allocate_tensors()  # CRASH: SIGSEGV from heap corruption

Root Cause

tile.cc:51: output_size->data[i] = SizeOfDimension(input, i) * multipliers_data[i]

13 × 330,382,100 = 2³² + 4 → overflows int32 to 4. Output allocated for 4 elements (32 bytes), but CopyMultipleTimes writes ~17 GB of attacker-controlled data from the model file.
