It's because the distribution maintains the kernel by backporting all the important fixes to its kernel. In other words, your Linux distribution makes sure that your Linux kernel is patched well and has all the bug fixes and important new features backported to it.

Why should I update Linux kernel?
The Linux Kernel is extremely stable. There is very little reason to update your kernel for stability's sake. Yes, there are always 'edge cases' that affect a very tiny percentage of servers. If your servers are stable, then a kernel update is more likely to introduce new issues, making things less stable, not more.
What is the difference between the Linux kernel and a Linux distribution?
A distribution is just the kernel (which may include distribution specific patches) plus all the extra programs that make it usable. The kernel is a central project, and is nominally the same in each distro, but most distros customize it a bit. ... A kernel is just interrupt handlers, device drivers, and system calls.
How do I use an old Linux kernel?
The simplest way to display your Grub is to press and hold the SHIFT button while booting. Show activity on this post. Holding down the shift key while booting, will display the Grub menu. You can now select an older kernel version.
Why are there different Linux distributions?
Because there are several vehicle manufacturers using the 'Linux engine' and each of them has many cars of different types and for different purposes. ... This is why Ubuntu, Debian, Fedora, SUSE, Manjaro and many other Linux-based operating systems (also called Linux distributions or Linux distros) exist.
Can kernel be updated?
The most of Linux system distributions update the kernel automatically to recommended and tested release. If you want to research your own copy of sources, compile it and run you can do it manually.
What happens if I update kernel?
Like any other software, Linux Kernel also needs an update periodically. ... Every update typically includes fixes to security loopholes, bug fixes to problems, better hardware compatibility, improved stability, more speed, and occasionally major updates also bring some new functions and features.
What are the main two distributions of Linux?
There are commercially-backed distributions, such as Fedora (Red Hat), openSUSE (SUSE) and Ubuntu (Canonical Ltd.), and entirely community-driven distributions, such as Debian, Slackware, Gentoo and Arch Linux.
Is Linux a kernel or OS?
Linux, in its nature, is not an operating system; it's a Kernel. The Kernel is part of the operating system – And the most crucial. For it to be an OS, it is supplied with GNU software and other additions giving us the name GNU/Linux. Linus Torvalds made Linux open source in 1992, one year after it's creation.
What are the major differences between Linux distros?
The first major difference between various Linux distributions is their target audiences and systems. For example, some distributions are customized for desktop systems, some distributions are customized for server systems, and some distributions are customized for old machines, and so on.
How do I find my old Linux kernel version?
The Linux kernel is much like the central brain of the operating system.
...
Simply add an option after the command:
- -a – Display all information.
- -o – Display the operating system (usually GNU/Linux)
- -r – Display kernel release.
- -v – Display kernel version (usually includes the base OS and time the kernel was compiled)
How do I revert back to my old Linux kernel?
Boot from previous kernel
- Hold the shift key when you see the Grub screen, to get to the grub options.
- you may have better luck holding the shift key all the time through the boot if you have a fast system.
- Choose Advanced options for Ubuntu.
How do I change the default Linux kernel?
As mentioned in the comments, you can set the default kernel to boot into using the grub-set-default X command, where X is the number of the kernel you want to boot into. In some distributions you can also set this number by editing the /etc/default/grub file and setting GRUB_DEFAULT=X , and then running update-grub .
