How to fix?

Upgrade SLES:15.7 python-base to version 2.7.18-150000.120.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python-base package and not the python-base package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

pip prior to version 26.1 would run self-update check functionality after installing wheel files which required importing well-known Python modules names. These module imports were intentionally deferred to increase startup time of the pip CLI. The patch changes self-update functionality to run before wheels are installed to prevent newly-installed modules from being imported shortly after the installation of a wheel package. Users should still review package contents prior to installation.
