>“Due to the layer at which the Linux kernel is in a system, almost any bug might be exploitable to compromise the security of the kernel… Because of this, the CVE assignment team is overly cautious and assign CVE numbers to any bugfix that they identify.”

"number of cves" is a useless metric, especially when it comes to the kernel.
If you're willing to stretch, missing but planned features also deny the use of said features since they haven't been added yet, and so are CVSS 1/Low vulnerabilities.
Resume-driven development for security researchers has never been easier!
That doesn't follow. In the extremely simple example, an adding service returning 1+1=3 has a bug, but it's not a possible DoS situation at all.

That's not what DoS is.
This whole situation with CVE assigning comes from the whole process being far from ideal. But it doesn't mean it's completely useless and doesn't follow any rules at all.
I do find it interesting though, that in the interest of transparency, every bugfix gets a CVE. Which ends up being a huge number… which will ultimately yield a more insecure environment as we’re getting conditioned to ignore/discount CVEs by the volume.
Over-reporting in this case seems to risk being counterproductive.
Kernel development is well-funded, both via grants and by direct employment at big tech companies, and if they wanted to properly triage and annotate vulnerabilities, and provide reasonable assessments of what is or isn't likely to be a security risk, they absolutely could. They could almost certainly go to Google and say "we need two people full-time on your payroll for this" and they would get it.
I don't want to dunk on them too much because they're generally doing God's work, but these absolutist security stances are not worth being taken seriously.
The frequency and severity of cyber attacks has increased to the point a much more cautious approach has become common. It's also easier to sell this work to management when you can point at the security tab on some tool and say "Look we need to patch these CVEs"
But, does that all of these being found now call into question, not the open source model logic itself, but the ability of human eyes to find security issues? These vulnerabilities have been sitting here for however long, but how many thousands of humans did not find them before AI?
For Linux, the threshold is nearer to the point of it being questionable whether a bug is even exploitable on a real production distro, compiled and run with any sort of sane configuration.
Long term I suspect that the purpose of the digital domain is going to end up being rethought. For instance connecting critical infrastructure to the internet has always been a terrible idea, and LLMs will just make that even more clear.
I suggest this post be renamed “A legion of vulnerabilities has been discovered…”
These get released every few weeks. Tons of CVEs. If a kernel developer farts in the forest, does anyone hear it?
August saw separate Debian kernel updates released four days apart. Does anyone even reboot that often?
I have three kernels installed over the last 45 days or so and I probably missed a few.
