#copyfail — Public Fediverse posts

Working on Week 11 lab write up. Need to add all the citations and references to my #CopyFail presentation slides (when did bibtex become biber???? God, I'm old.)

Also finishing up the course reflection for this, my final #CyberSecurity course. Five courses, 20 credit hours of master's level graduate courses over about 15 months.

So, ofc, I'm going to start a practicum for Orten Gillingham #reading instruction from next week. OG+#EnglishLearners = great?

spent much of the day working on my #CyberSecurity presentation about #CopyFail #Linux #kernel vulnerability. About 20 slides; I have 7 minutes. No problem.

Tomorrow, I need to finish the other homework for the class.

#Linux got bitten by crypto-related page cache vulnerabilities in recent weeks. They had rather boring names: #CopyFail #DirtyFrag #Fragnesia

The #FreeBSD community is fixing this by naming their own bug of this class #BUMSRAKETE.

(Now, if you ran the name through a translator and are questioning its legitimacy: It's as real as the person that inspired the bug report's style, unfortunately.)

"[…] The "#CopyFail" vulnerability presented a unique challenge for us. Despite our practice of deploying #Linux patch updates every two weeks, we remained vulnerable because a month-old mainline fix had yet to be backported to our primary #kernel line. Despite that, we were still able to roll out patched kernels within hours of the backport's release. In the interim, #bpf-lsm provided a surgical, no-reboot mitigation that secured our fleet. […]"

Если вы всё ещё беспокоитесь о [copy.fail](https://copy.fail/) в своих `kubernetes` кластерах - вот изи-фикс.

Маленький `DaemonSet`, грузит BPF-LSM хук на `socket_create` и режет любые попытки открыть `AF_ALG`. Без ребута, без пересборки ядра, без правки cmdline.
Работает на Talos Linux, где `rmmod` архитектурно недоступен (SELinux + lockdown + контроллер не умеет unload).

Ставится одной командой:
`kubectl apply -f`
