Summary

Reference binding to null pointer in `MatrixDiag*` ops

Details

Impact

The implementation of MatrixDiag* operations does not validate that the tensor arguments are non-empty:

      num_rows = context->input(2).flat<int32>()(0);
      num_cols = context->input(3).flat<int32>()(0);
      padding_value = context->input(4).flat<T>()(0);

Thus, users can trigger null pointer dereferences if any of the above tensors are null:

import tensorflow as tf

d = tf.convert_to_tensor([],dtype=tf.float32)
p = tf.convert_to_tensor([],dtype=tf.float32)
tf.raw_ops.MatrixDiagV2(diagonal=d, k=0, num_rows=0, num_cols=0, padding_value=p)

Changing from tf.raw_ops.MatrixDiagV2 to tf.raw_ops.MatrixDiagV3 still reproduces the issue.

Patches

We have patched the issue in GitHub commit a7116dd3913c4a4afd2a3a938573aa7c785fdfc6.

The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.
