This, even though I've tagged this as an enhancement, is actually an issue. Zen Kernel users could have vulns fixed in v5.19 still lurking at x86_64 ring 0. I am one of those users, and the kernel I use being out of date is a major issue for me. Please fix.
zen-sources is not updated at the pace you are seeking. We keep pace with zfs-kmod support. If you need to have the latest and greatest you can maintain a copy in a private overlay or you will need to switch to a security supported sources such as gentoo-sources.
