Are all Debian 11 systems automatically vulnerable to CVE-2023-38408?

I really really hope I'm wrong here, but it seems that Debian 11 has a vulnerable version of OpenSSH. My OpenSSH banner reports my OpenSSH version is: 8.4p1 Debian 5+deb11u1 I checked with sshd and it reports the same version. According to this CVE-2023-38408 ANY version before 9.3p2 is vulnerable. I tried sudo apt update && sudo apt full-upgrade but it did not update the OpenSSH version..
