Could you please point me to where those fixes were ported? You can also check who did the actual update. For 2.2.10-2+deb11u2. [1] it's Salvatore Bonaccorso and for 2.2.6-2+deb10u3 [2] it's him again. But I can answer your question as well. You can get the corresponding debian files, expat_2.2.10-2+deb11u2.debian.tar.xz [3] and expat_2.2.6-2+deb10u3.debian.tar.xz [4]. For example, if you download the former, under debian/patches/ you will find the backported patches. File naming follows the commit messages. That is, for this commit it's the lib-Detect-and-prevent-troublesome-left-shifts-in-fu.patch file.
