432 Linux kernel CVEs

Hello,

As observed on social media[1], the Linux kernel<br>published 432 CVEs between 2026-07-19T09:09 and<br>2026-07-20T16:27 (in addition to the >40 other CVEs<br>already published this month alone):

https://lore.kernel.org/linux-cve-announce/

I understand the position that CVEs were always a<br>flawed way to track or prioritize security changes,<br>and "but it's the only thing we have" isn't a great<br>argument in favor.

But this onslaught really shows it's not feasible to<br>attempt to prioritize individual kernel changes.

You might attempt to process this large set of changes<br>by pointing an LLM at the intake and asking it to<br>prioritize them for your environment based on the<br>additional context you may be able to feed it with,<br>but if it spits out a dozen today and another 25 the<br>next, you haven't won much.

Alternatively, you might shrug and wait to see which<br>of these will get a logo and catchy name in the next<br>few weeks and then try to focus on those.

Another approach might be to sit back, have a nice cup<br>of zen, and just always pull all updates and then<br>update your entire fleet of systems on a weekly basis,<br>which, yes, I sure would like to be able to do, but<br>reality keeps getting in my way.

I'm not sure what to do here going forward.

-Jan
