How to fix?

Upgrade tensorflow-cpu to version 2.2.1, 2.3.1 or higher.

Overview

tensorflow-cpu is a machine learning framework.

Affected versions of this package are vulnerable to Uninitialized Memory Exposure. The implementation of dlpack.to_dlpack can be made to use uninitialized memory resulting in further memory corruption. This is because the pybind11 glue code assumes that the argument is a tensor. However, there is nothing stopping users from passing in a Python object instead of a tensor.The uninitialized memory address is due to a reinterpret_castSince the PyObject is a Python object, not a TensorFlow Tensor, the cast to EagerTensor fails.
