If you don't want to wait for 6.1.67-1 to arrive in Bookworm stable, it is available in bookworm-proposed-updates [1][2], so one workaround would be to temporarily add that repository [3] to apt sources before upgrading. Debian point release 12.4 has just gone out, so right now there are relatively few other packages in bookworm-proposed-updates which might have complicated the situation.
