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.
