How do I check if my Ubuntu kernel has already been patched?

And if it hasn’t, any tips on how to upgrade?
There's a super long list there, but most everything has been updated or superceded.
The standard (updated) kernels are:
* Focal: 5.4.0-174.193
* Jammy: 5.15.0-101.111
* Mantic: 6.5.0-26.26
Edit: Oh it looks like the generic kernel is the one named just "linux" and also has 5.15.0... as the patched version on Jammy
