Null dereference in Grappler's `TrySimplify`
Impact
The implementation of TrySimplify has undefined behavior due to dereferencing a null pointer in corner cases that
result in optimizing a node with no inputs.
Patches
We have patched the issue in GitHub commit e6340f0665d53716ef3197ada88936c2a5f7a2d3.
The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.
