@kernelconfig only partially related, but if you're ever in need of looking up the values of configurations for common Linux distro kernels, you can check:

A bit of shameless self promotion but I do find it genuinely useful.

OpenPrinting/CUPS project decided to publish my related-but-different finding (in code that is about to all go away) https://github.com/OpenPrinting/cups-filters/security/advisories/GHSA-rq86-c7g6-r2h8

So in an insight it's obvious why the details leaked. Someone wanted to cut this drama short.

Some soft skills insight I gathered over my long career as a security researcher and shitposter:

• When you insult the devs on your security bug reports when they dare not understanding the impact of your awesome bug on the first try, they turn non cooperative. Their main focus shifts from fixing the bug to avoid interacting with you.
• When the disclosure process isn't going well, going to your community to stir the pot isn't going to make things go easier, especially when you're overevaluating the impact of your bug.

Thanks for following my Ted speech

Mark Zuckerberg says the individual work of most creators isn’t valuable enough for it to matter. First of all, FUCK you, Mark. Another billionaire thinks an artist's work, such as images/art, books, music, text, and other things, has no value. People can't even browse IG or FB without downloading your shity app. Why don't you allow everyone to scrap those IG/FB posts? This guy is a menace to society and doesn't care if someone will lose their livelihood so that he can have another 100 billion.

Unath RCE in CUPS which triggers after a print job - affects most desktop linux flavors https://www.evilsocket.net/2024/09/26/Attacking-UNIX-systems-via-CUPS-Part-I/

Hackers showed me (there's video) how a website vulnerability let them locate, unlock, honk the horn, start ignition of any of millions Kias in seconds, just by reading a car's license plate.

They found similar bugs for a dozen carmakers over the last two years.

I am teaching a course on Linux kernel exploitation, and I mentioned the indeterminism of the objects in the physmap to the class. An example I showed is the struct task_struct of the first process, systemd. Even with KASLR disabled, that address will always differ on every boot. I said the CPU is fundamentally indeterministic, but my answer is too vague. I will read the Linux kernel initialization code to see if I discover anything interesting. Still, I would appreciate it if someone could give me a more detailed answer or point me in the right direction.

@karl No worries, I think compiling The Ways a Bug Can Die would be an interesting, non-trivial project by itself!

@karl Note that you just mentioned at least another way (deletion) a vuln can "disappear" :) There are probably many others (e.g. OS restricts API required for exploitation)...

The first simulated image of a black hole was calculated with an IBM 7040 computer using 1960 punch cards and hand-plotted by French astrophysicist Jean-Pierre Luminet in 1978.
