How to fix?

Upgrade SLES:15.1 python3-tk to version 3.6.10-3.42.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-tk package and not the python3-tk package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.
