## Overview

### Impact
An input `token` that is not a UTF-8 bytestring will trigger a `CHECK` fail in [`tf.raw_ops.PyFunc`](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/lib/core/py_func.cc).

```python
import tensorflow as tf

value = tf.constant(value=[1,2])
token = b'\xb0'
dataType = [tf.int32]

tf.raw_ops.PyFunc(input=value,token=token,Tout=dataType)
```

### Patches
We have patched the issue in GitHub commit [9f03a9d3bafe902c1e6beb105b2f24172f238645](https://github.com/tensorflow/tensorflow/commit/9f03a9d3bafe902c1e6beb105b2f24172f238645).

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.
