The fact that you had to take a whole paragraph to explain the contortionist arrival at something that isn't even really super clear after you explained it (you kinda pointed the finger both at end users and at distro maintainers simultaneously) and essentially boils down to "well, you as the end user need to be following kernel CVE's and can't trust distro maintainers to do it" does in fact indicate that there is a deeper issue at play here. You might say "well, there's no implicit chain of trust here". You might be right, but is that really the most effective way of doing things? Of course Linux is Use it at your Own Risk, but is there not a concept of "we as a collective community should get together and try not to drop the ball on some serious shit?"
In terms of something actionable, and maybe someone more well versed in how the distros work can tell me why this is a bad idea, but shouldn't there be a documented process and channel for critical CVE's to be bubbled out to distro maintainers who then have some sort of SLA for patching them and sending them downstream to end users? Perhaps incentives are not aligned to produce this outcome.
