You can create a backport PR as regular one: create a branch in your fork of jdk18u, apply the changeset, commit and push the branch. Now create a PR with the title *Backport `<commit-hash>`* where `commit-hash` is the hash of the commit you're backporting, which is `8c460b043e1cbaf1f2d74958033bb24dea66a390` in this case.
