CWEhttps://cwe.mitre.org/data/definitions/415.html

psutil (aka python-psutil) through 5.6.5 can have a double free. This occurs because of refcount mishandling within a while or for loop that converts system data into a Python object.

Weakness

The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
