If you install security fixes automatically - there is an option to do this - then the running kernel version will not change until you reboot the machine. Others have pointed out that you have to opt-in to upgrade backports packages. If you choose to use the bookworm-backports version of the kernel: 6.12 is the LTS version. Unless there is some catastrophic security bug that affects it, Debian will carry on using the LTS version and will not move forwards to 6.13 or whatever. Updates to 6.12 will continue. The backport comes from the kernel in Debian testing but built using the tools in Debian stable. That kernel is 6.12. When testing becomes stable in a few months time as Debian 13 (Trixie), you will still have 6.12. A dist upgrade to Debian 13 will update all packages but the base kernel version is still likely to be 6.12 for the lifetime of Trixie (unless there are security changes which force a move of kernel version.)
