TensorFlow, an open-source machine learning platform, has a vulnerability (CVE-2021-29535) where attackers can cause a heap buffer overflow (a memory safety error where code writes beyond allocated memory) in the `QuantizedMul` function by providing invalid threshold values for quantization. The bug occurs because the code assumes input values are always valid and tries to access data that doesn't exist when empty tensors (multi-dimensional arrays) are passed in.
