NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-psutil package and not the python3-psutil package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
