GA is the kernel a release launched with, while HWE or Hardware Enablement kernels are a set of newer kernel that become available in the current LTS release as these newer kernels are released with subsequent Ubuntu versions, up until the next LTS release.

There will be Livepatch support for HWE kernels across a limited combination of kernel flavour (variants), kernel version, and Ubuntu release as detailed above.

See this page to better understand why your kernel might not be supported.
