CVE-2022-41911 Invalid char to bool conversion when printing a tensor in Tensorflow

TensorFlow is an open source platform for machine learning. When printing a tensor, we get it's data as a const char array since that's the underlying storage and then we typecast it to the element type. However, conversions from char to bool are undefined if the char is not 0 or 1, so...
