    Greatly appreciated the candor. I've included a few slides into text that i thought were eye-opening to me:

    From his Kernel Recipes 2026 slide on Mythos

    ```

      Mythos's 79 vulnerabilities:
      24 - no detail at all "something crashed"
      14 - not a bug at all
      3 - totally made up data
      15 - already fixed in latest release
        - 11 by others
        - 4 by anthropic
      20 - fixes were needed
        - 7 "assume a malicious filesystem image"
        - 2 "assume you can inject a malicious network packet into the middle of the stack"
        - 2 "NOMMU"
        - 6 sctp networking issues for untrusted devices
        - 2 ipv6 minor network issues 
        - 1 gpu driver for local malicious user
    
    ```

    GHK called this "10 'real' bugfixes", which to me sounds like there's a wild hype machine around these companies and uncritical parroting of every press release they make that falls apart when you engage the affected real experts.

      We’ve seen this in a few open source repos we voluntarily manage security on. They’re not massive repos, but big enough they get attention from security researchers.

      Most of the real low hanging fruit was picked up by humans years ago. When doing automated scanning, the majority of stuff is overly-verbose nonsense which takes hours of expert human labour to understand, test, and discard.

      Reading through a Claude generated false positive is absolutely excruciating, because it is absolutely determined that what it’s found is justified. Often you’ll receive very long accompanying “proof of concept” code which demonstrates absolutely wild scenarios. It’s especially frustrating when you’re volunteering your time for a project, and a well-meaning contributor submits the report without the technical nous to understand why you’re rejecting it.

        I think the way to handle this is to just feed it into another AI agent (a better one) and ask it how serious the issue actually is. Fight fire with fire!

          That&#x27;s somehow what <a href="https:&#x2F;&#x2F;sashiko.dev" rel="nofollow">https:&#x2F;&#x2F;sashiko.dev is.
