How often a new kernel is updated on Kubuntu?

It depends. and follows what Ubuntu does, since it is all the same distro.

All releases get security fixes to kernels regularly, as needed. These are not new major versions, however. They are the same version, rebuilt with fixes to the code. So no new hardware support or features.

Non-LTS stick to the same kernel version though its 9-month lifespan. No version bumps at all, but with security updates.

LTS start out with one kernel at the beginning. 22.04 starts with the 5.15.0 kernel.
When the second updated iso image is made available (the so-called "point" release --22.04.2) the following February, the kernel from then-current non-LTS is added as the default. 5.19.0 for Jammy, in this case.
This DOES provide new hardware support and features.

This happens every 6 months until the next LTS release.
In between, you do get patched versions as security fixes are added.

22.04 users should see the 6.2 kernel around August.
Users who installed *buntu desktops with the original 22.04 image from April may not see kernel upgrades, though all desktop users are supposed to. But this is easily fixed.
Server installs from the original ISO by design stay with the original "GA" kernel by default

The fix is to enable HWE right?

Yup

sudo apt install --install-recommends linux-generic-hwe-22.04

Just had one yesterday, 5/22/23. Previously, for this year: 4/25/23 4/18/23 3/28/23 3/13/23 2/23/23

Grepping the logs in /var/log, apt and dist-upgrade, tells me there were 23 new kernels in the last year in this 22.10 install.

The 5.19.0 kernel is on its 42nd build, though a lot of those will have been done in pre-release.
The OG 5.15.0 in 22.04 is at number 72.

Thanks for answering.

cat /etc/os-release

Will show you what your Kubuntu version is.

You can also use the command

uname -r

or

uname -a

The first one will tell you the current kernel in use, the second give a little more info.
