Impact

Another instance of CVE-2022-35991, where TensorListScatter and TensorListScatterV2 crash via non scalar inputs inelement_shape, was found in eager mode and fixed.

```python

import tensorflow as tf

arg_0=tf.random.uniform(shape=(2, 2, 2), dtype=tf.float16, maxval=None)

arg_1=tf.random.uniform(shape=(2, 2, 2), dtype=tf.int32, maxval=65536)

arg_2=tf.random.uniform(shape=(2, 2, 2), dtype=tf.int32, maxval=65536)

arg_3=''

tf.raw_ops.TensorListScatter(tensor=arg_0, indices=arg_1,

element_shape=arg_2, name=arg_3)

Patches

We have patched the issue in GitHub commit [bf9932fc907aff0e9e8cccf769e8b00d30fd81a1](https://github.com/tensorflow/tensorflow/commit/bf9932fc907aff0e9e8cccf769e8b00d30fd81a1).

The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range.
