Affected scope and exposure questions

The current feed maps tensorflow (pypi), tensorflow-cpu (pypi), tensorflow-gpu (pypi). Check affected ranges and fixed versions before updating.

Mapped affected packages and fixed versions
Package	Affected range	Fixed version
tensorflowpypi	>=0 <2.11.1	2.11.1
tensorflow-cpupypi	>=0 <2.11.1	2.11.1
tensorflow-gpupypi	>=0 <2.11.1	2.11.1

Recommended response

Check inventory. Check lockfiles and deployed manifests for tensorflow, tensorflow-cpu, tensorflow-gpu.

Upstream source description

### Impact When ctx->step_containter() is a null ptr, the Lookup function will be executed with a null pointer. ```python import tensorflow as tf tf.raw_ops.TensorArrayConcatV2(handle=['a', 'b'], flow_in = 0.1, dtype=tf.int32, element_shape_except0=1) ``` ### Patches We have patched the issue in GitHub commit [239139d2ae6a81ae9ba499ad78b56d9b2931538a](https://github.com/tensorflow/tensorflow/commit/239139d2ae6a81ae9ba499ad78b56d9b2931538a). The fix will be included in TensorFlow 2.12.0. We will also cherrypick this commit on TensorFlow 2.11.1 ### For more information Please consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions. ### Attribution This vulnerability has been reported by Yu Tian
