🐞 Linus Torvalds says AI-powered bug hunters have made Linux security mailing list ‘almost entirely unmanageable’

“So just to make it really clear: If you found a bug using AI tools, the chances are somebody else found it too. If you actually want to add value, read the documentation, create a patch too, and add some real value on *top* of what the AI did. Don't be the drive-by ‘send a random report with no real understanding’ kind of person. OK?”

RubyGems suspends new Signups after Hundreds of Malicious Packages are Uploaded.

RubyGems, the standard package manager for the Ruby programming language, has temporarily paused account sign ups following what has been described as a "major malicious attack."

"We're dealing with a major malicious attack on Ruby Gems right now," Maciej Mensfeld, senior product manager for software supply chain security at Mend.io, said in a post on X. "Signups are paused for the time being. Hundreds of packages involved – mostly targeting us, but some carrying exploits."

Peter G. Neumann, renowned computer scientist, ARPANET/Internet pioneer and expert on technology risks, working at SRI International since 1971, has died at age 93. Peace. He has been my friend and colleague for over half a century. He will be greatly missed.

There's apparently another Linux LPE.
DirtyDecrypt, also known as DirtyCBC, is a variant of CopyFail / DirtyFrag / Fragnesia.
I suspect it may be CVE-2026-31635.
Patches (change < to >) were committed on April 8, 2026 and also on April 18, 2026 as beee051f259acd286fed64c32c2b31e6f5097eb5 and e2f1a80d8b1ed6a5ae585a399c2b46500bdcc305

I have not been able to get it to actually work on any Linux distro that I've tried.
(Edit: Fedora and mainline Linux repro fine)

Enjoy! Constructive criticism is always appreciated.

DOMPurify 3.4.4 is out with again several small in-depth improvements.

These include added stability for IN_PLACE sanitization, improved handling of cross-realm nodes and several newly permitted elements and attributes.

TIL that one of the diagnostic clues for autism is "Thinks about their special interests outside of the time when actually engaging with special interests."

And I'm like... what? What else do you think about?...

That's a wrap on Pwn2Own Berlin 2026! 🏆 $1,298,250 awarded. 47 unique 0-days. 3 days of absolute chaos. And talk about main character energy - congrats to DEVCORE for claiming Master of Pwn with 50.5 points and $505,000 - they never slowed down. See you next year! #Pwn2Own #P2OBerlin

RE: https://infosec.exchange/@thezdi/116585566164605071

* Seems many of the Browser exploits couldn't be demoed due to bad luck/last-minute fixes. Really sorry for the participants :( great research!
* No V8 (and Chrome?) submissions for the 2nd year in a row
* Orange's Edge chain sounds wild, very curious for details!
Thanks for running #Pwn2Own @thezdi

Exclusive: Fast16 malware has raised questions about what it was designed to do. Researchers at Symantec finally confirm it was subverting software used to simulate nuclear weapons explosions. Nuclear experts also tell me Iran was the likely target and explain how it impacted nuclear weapons tests. Fast16 wasn't aimed at sabotaging nuclear weapons themselves, but was only designed to alter data being fed to engineers from software used to simulate nuclear explosions tests. The goal was to trick engineers into believing their tests were failing to create confusion and slow down weapons program. Fast16 and Stuxnet were similar in that they both fed false data to engineers. But Stuxnet also physically altered centrifuges while tricking engineers into believing the devices were fine. New analysis from me also shows the two codes were contemporaneous, not separated by years.

Here's my story, which contains a link to a timeline showing how they were being developed around the same time, likely as part of a multi-pronged operation to slow down Iran's nuclear program.
