How to fix?

There is no fixed version for RHEL:9 ubi9/python-312.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ubi9/python-312 package and not the ubi9/python-312 package as distributed by RHEL. See How to fix? for RHEL:9 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.
