Yes
by Vanessa Van Basten

https://subsoundrecords.bandcamp.com/album/yes

Ah, figo: they are back.
Gli alfieri primi del post-rock italiano tornano a farsi sentire!

La "La Stanza di Swedenborg" (https://www.youtube.com/watch?v=fPd2knSl9AQ) l’ho consumata. No, davvero: ci ho praticamente vissuto dentro, aspettando la mia seduta spiritica per uscirne ...e forse non sono mai uscito del tutto.

et effectivement cela fonctionne avec le dernier kernel patché pour copy.fail ( AppArmor off )

Sam James (Gentoo Security) a posté sur oss-sec et lui a trouvé un autre petit surnom : "CopyFail 3.0" 😅
👇
https://seclists.org/oss-sec/2026/q2/515

(Le patch est soumis sur netdev mais pas encore mergé dans l'arbre de Linus: donc toujours pas dispo dans les kernels stables des distros vulnérables.)

CloudLinux a déjà publié une advisory et annonce des patches KernelCare en route.

🤪 🔥
et c'est reparti pour un tour : #fragnesia le petit frère de DirtyFrag (même famille ESP/XFRM, même mitigation rmmod esp4 esp6 rxrpc, même page cache qui se fait défoncer, just trust me bro).

Bonne nouvelle : si t'avais blocklisté les modules « au cas où », t'es OK.

Mauvaise nouvelle : si t'as "juste" patché DirtyFrag , il te faut le patch Fragnesia aussi.

"Fragnesia is a universal Linux local privilege escalation exploit, discovered by William Bowling with the V12 team. Fragnesia is a member of the Dirty Frag vulnerability class. "

So I’ve just had a quick play with this and yes, it works. Essentially BitLocker has a backdoor. https://github.com/Nightmare-Eclipse/YellowKey

Mitigation = BitLocker PIN and BIOS password lock.
