CVE-2021-29544: TensorFlow is an end-to-end open source platform for machine learning. An attacker can trigger a denial of service via a

TensorFlow has a vulnerability where an attacker can crash the system (a denial of service, or DoS attack) by sending specially crafted data to a specific function called `tf.raw_ops.QuantizeAndDequantizeV4Grad`. The bug happens because the function doesn't check that its input data (called tensors, which are multi-dimensional arrays) has the correct structure, causing the program to fail when it tries to process them.
