I assume the patch will be backported and there will be a point release .30.? including it, but bullseye will probably sticks with 2.30.

However, you can use bullseye-backports to get 2.34.1 if you want: See https://packages.debian.org/git

Edit: None of the debian versions have the patch yet: https://security-tracker.debian.org/tracker/CVE-2022-24765
