The possible range of kernels is quite large. You can actually run a kernel *much* older or newer than the one which comes with your Debian release. Buster (Debian 10) ships with a 4.19 kernel, but you can run it with a 3.2 kernel. Debian 9 can run with a kernel even older than that; my VPS for example is on a 2.6 kernel, and I've got it up to Debian 9, which is as far as I can go on that kernel. https://www.debian.org/releases/buster/amd64/release-notes/ch-information.en.html#glibc-and-linux
