How to fix?

There is no fixed version for RHEL:7 tkinter.

NVD Description

Note: Versions mentioned in the description apply only to the upstream tkinter package and not the tkinter package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The fix for CVE-2026-0672, which rejected control characters in http.cookies.Morsel, was incomplete. The Morsel.update(), |= operator, and unpickling paths were not patched, allowing control characters to bypass input validation. Additionally, BaseCookie.js_output() lacked the output validation applied to BaseCookie.output().
