Copyfail root escalation error

[retrovirus-007 at juno.com]

Hello Linux-libre,

https://arstechnica.com/security/2026/04/as-the-most-severe-linux-threat-in-years-surfaces-the-world-scrambles/

I read online that an certain CopyFail error is found by some AI tool. So far, news sites state that major Linux distributions are affected as targets. According to research, it provides a exploit run test, but I couldn't trust its procedure safety.

If I have a certain Linux-libre kernel version, should I be safe enough? I don't use the affected Linux distributions, but I couldn't be sure.
