+## TFSA-2022-145: OOB seg fault in `DynamicStitch` due to missing validation
+
+### CVE Number
+CVE-2022-41883
+
+### Impact
+ [`tf.raw_ops.DynamicStitch`](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/kernels/dynamic_stitch_op.cc) specifies input sizes when it is [registered](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/ops/data_flow_ops.cc). 
+```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](https://github.com/tensorflow/tensorflow/commit/f5381e0e10b5a61344109c1b7c174c68110f7629).
+
+The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, as it is also affected and still in supported range.
