There’s the backports repository.

https://backports.debian.org/

Or just understand that Debian stable can be moved to Debian testing (or even Debian unstable if even 2 weeks is too long) trivially. The best decision that Debian has ever made is not to distribute or advocate for testing as a rolling distribution, because if you're too ignorant to change your repo to testing, you're really too ignorant to be using testing.

Admitting that getting 6.18 on Debian is some sort of insurmountable mountain is not something I would do in public while trying to show off my expertise. I'm not running it, because I don't need a kernel that's been out for 5 minutes and offers me nothing that can't wait a month or two. I'm running what's current on testing, which is 6.17.13. It's about a minute of work to switch to testing. I run stable on all my servers, and testing on my laptops, it is a triviality. But to all you bleeding edge software people, it's somehow rocket surgery.

So, it's really still Windows, then. I assume you've moved from spending years ranting about how Linux people were purist server admins and Windows was for users and just worked, and now you've chosen the same posture after being pushed out of Windows.

> Debian stable is for purists or server admins. Not for users.

You're not a typical user. Most users want a functional computer, not the largest numbers they can find.
