CVE-2021-37638: TensorFlow is an end-to-end open source platform for machine learning. Sending invalid argument for `row_partition_types

A vulnerability in TensorFlow (a machine learning platform) allows attackers to crash the program by sending an invalid empty list to the `tf.raw_ops.RaggedTensorToTensor` function, which tries to access the first element without checking if the list is empty first, causing undefined behavior (unpredictable program actions). This is a null pointer dereference (attempting to use a memory location that contains no valid data).
