You’re good. That’s the latest image, it’s just the confusing Debian version scheme where the package version is not the same as the kernel version. Debian package version 6.1.0-17 = kernel version 6.1.69-1

See:

$ uname -a
Linux debian12 6.1.0-17-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.69-1 (2023-12-30) x86_64 GNU/Linux

And:

$ dpkg-query --list linux-image-6.1.0-17-amd64
Desired=Unknown/Install/Remove/Purge/Hold
