I've fixed the change log commit message like so:

Nitpick; I've used the more conventional indentation for patches:

--8<---------------cut here---------------start------------->8---
              (patches
               (search-patches "heimdal-CVE-2022-45142.patch"))
--8<---------------cut here---------------end--------------->8---

Thank you!
