Null pointer dereference in `CompressElement`
Impact
It is possible to trigger a null pointer dereference in TensorFlow by passing an invalid input to tf.raw_ops.CompressElement:
import tensorflow as tf
tf.raw_ops.CompressElement(components=[[]])
The implementation was accessing the size of a buffer obtained from the return of a separate function call before validating that said buffer is valid.
Patches
We have patched the issue in GitHub commit 5dc7f6981fdaf74c8c5be41f393df705841fb7c5.
The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.
