Impact

TensorFlow's type inference can cause a heap OOB read as the bounds checking is done in a DCHECK (which is a no-op during production):
cc
if (node t.type id() != TFT UNSET) {
 int ix = input idx[i];
 DCHECK(ix < node t.args size())
   << "input " << i << " should have an output " << ix
   << " but instead only has " << node t.args size()
   << " outputs: " << node t.DebugString();
 input types.emplace back(node t.args(ix));
 // ...
}
An attacker can control input idx such that ix would be larger than the number of values in node t.args.

Patches

We have patched the issue in GitHub commit c99d98cd189839dcf51aee94e7437b54b31f8abd.
The fix will be included in TensorFlow 2.8.0. This is the only affected version.
