Summary

TensorFlow may dereference a null pointer when decoding a tensor from protobuf if attributes of some mutable arguments to certain operations are missing from the proto. The check guarding this is a DCHECK, which is a no-op in production builds and an assertion failure in debug builds, so execution either reaches the null dereference or crashes.

Mitigation

The fix will be included in TensorFlow 2.8.0. The commit will also be cherrypicked to TensorFlow 2.7.1 and TensorFlow 2.6.3.
