Description

TensorFlow has Null Pointer Error in SparseSparseMaximum

Impact

When SparseSparseMaximum is given invalid sparse tensors as inputs, it can give an NPE.

```python

import tensorflow as tf

tf.raw_ops.SparseSparseMaximum(

a_indices=[[1]],

a_values =[ 0.1 ],

a_shape = [2],

b_indices=[[]],

b_values =[2 ],

b_shape = [2],

)

```

Patches

We have patched the issue in GitHub commit [5e0ecfb42f5f65629fd7a4edd6c4afe7ff0feb04](https://github.com/tensorflow/tensorflow/commit/5e0ecfb42f5f65629fd7a4edd6c4afe7ff0feb04).

The fix will be included in TensorFlow 2.12. We will also cherrypick this commit on TensorFlow 2.11.1.
