CVE-2021-29530: TensorFlow is an end-to-end open source platform for machine learning. An attacker can trigger a null pointer dereferenc

TensorFlow (an open source machine learning platform) has a vulnerability where an attacker can cause a null pointer dereference (accessing memory that doesn't exist, crashing the program) by providing invalid input to a specific function called `tf.raw_ops.SparseMatrixSparseCholesky`. The problem occurs because the code fails to properly validate inputs due to a macro that returns early from a validation function without stopping the main code from continuing.
