TensorFlow vulnerable to `CHECK`-fail in `tensorflow::full_type::SubstituteFromAttrs`

Impact

When tensorflow::full_type::SubstituteFromAttrs receives a FullTypeDef& t that is not exactly three args, it triggers a CHECK-fail instead of returning a status.

Status SubstituteForEach(AttrMap& attrs, FullTypeDef& t) {
  DCHECK_EQ(t.args_size(), 3);

  const auto& cont = t.args(0);
  const auto& tmpl = t.args(1);
  const auto& t_var = t.args(2);

Patches

We have patched the issue in GitHub commit 6104f0d4091c260ce9352f9155f7e9b725eab012.
The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
