Summary
Null pointer dereference in `RaggedTensorToTensor`
Details

Impact

Sending invalid argument for row_partition_types of tf.raw_ops.RaggedTensorToTensor API results in a null pointer dereference and undefined behavior:

```python import tensorflow as tf

tf.raw_ops.RaggedTensorToTensor( shape=1, values=10, default_value=21, row_partition_tensors=tf.constant([0,0,0,0]), row_partition_types=[]) ```

The implementation accesses the first element of a user supplied list of values without validating that the provided list is not empty.

Patches

We have patched the issue in GitHub commit 301ae88b331d37a2a16159b65b255f4f9eb39314.

The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.
