Affected packages
• PyPI tensorflow: >= 2.10.0, < 2.10.1 → fixed in 2.10.1
• PyPI tensorflow-cpu: >= 2.10.0, < 2.10.1 → fixed in 2.10.1
• PyPI tensorflow-gpu: >= 2.10.0, < 2.10.1 → fixed in 2.10.1
Description
Impact
`tf.raw_ops.DynamicStitch` specifies input sizes when it is registered.
```cpp
REGISTER_OP("DynamicStitch")
.Input("indices: N * int32")
.Input("data: N * T")
.Output("merged: T")
.Attr("N : int >= 1")
.Attr("T : type")
.SetShapeFn(DynamicStitchShapeFunction);
```
When it receives a differing number of inputs, such as when it is called with an `indices` size 1 and a `data` size 2, it will crash.
```python
import tensorflow as tf
indices = 1*[tf.random.uniform([1,2], dtype=tf.dtypes.int32, maxval=100)]
indices = [tf.constant([[0, 1]]),]
data = 2*[tf.random.uniform([1,2], dtype=tf.dtypes.float32, maxval=100)]
data = [tf.constant([[5, 6]]), tf.constant([[7, 8]])]
tf.raw_ops.DynamicStitch(
indices=indices,
data=data)
```
Patches
We have patched the issue in GitHub commit f5381e0e10b5a61344109c1b7c174c68110f7629.
The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1 as this is also affected.
