Csináltam egy merészet.

Van egy Lenovo Yoga 11e tablet PC-m. De, Linux alatt egyszerűen sosem működött a tablet funkció.

Hat éve van nálam, de együtt tudtam ezzel élni, mert igazából nekem egy valóban kis laptop kellett utazásokhoz, ha ügyet kellett oldanom alapon.

Sosem használtam ki tabletként. Még Windows alatt sem. (Igaz, Windowst csak és kizárólag az ősöreg, de LifeTime Garmin Nuvi GPS-em frissítéséhez használok egyedül, mert nincs kedvem kerülő utat keresni rá.)

De, úgy voltam vele, hogy ha már van mindenféle CLI-s AI agent, akkor teszek egy próbát azzal is.

Oda adtam a Claude AI CLI agentjének sudo joggal együtt, hogy... oldja meg, ha tudja.

Dolgozik bőszen. És, igazából nem csak azért nem félek, hogy elront valamit, mert nincs semmi szenzitív azon a gépen és pikk-pakk újra telepítem és kész.
De, azért sem, mert egyszerűen egy netes keresést nem tud megcsinálni anélkül, hogy minden oldalra külön rá ne kérdezne, hogy engem-e.

...és ugyanez minden lépésnél itt is. Egyszerűen nem tudok normálisan gépelni, mert a másik monitoron az ssh-ban folyamatosna nyomkodnom kell az entert a jóváhagyások miatt.

Kíváncsi leszek, mi lesz a vége!

@BrideOfLinux I enjoyed your article – thanks. Discovered three months after publication via <https://vermaden.wordpress.com/2026/05/04/valuable-news-2026-05-04/>.

Just one thing:

"… Isn’t this exactly what the Open Source Security Foundation was established to handle in the wake of OpenSSL’s difficulties?"

I 'm not certain. The roadmap at <https://openssf.org/about/> begins:

"The OpenSSF strategy is outlined across three key areas:

We will be a Catalyst for Change, we will Educate and Empower the Modern Developer, and we will be an Ecosystem Leader. …"

There's much more than a roadmap – and I didn't attempt to digest the charter (it's difficult to read, with the watermark) – it's difficult to tell why the OSSF was established, and so on. I don't doubt that the Foundation does great work, there's just a lot to take in. @openssf

In the case of sudo: I imagine that the media was a catalyst for change. Some time between mid-February and 3rd March, the plea for sponsorship disappeared:

― <https://web.archive.org/web/20260305141311/https://www.millert.dev/>.

(I recall reading the article in The Register, which was discussed in Reddit <https://old.reddit.com/r/programming/duplicates/1qwsvh9/sudos_maintainer_needs_resources_to_keep_utility/>, and so on.)

The truth about #sudo: https://security.stackexchange.com/questions/232924/is-sudo-almost-useless

> Sudo has no real security purpose against a malicious third-party. [...]

> In the past I believed it was actually a security control to prevent escalation of privilege and make attacks harder [...], but that's actually false. [...]

> The only purpose of sudo is to protect you from yourself, that is, to avoid messing up your system by mistake

One of sudo's co-author also gives his opinion, go check it out!

Is `sudo` almost useless?

Once an attacker has a shell as your sudoer user (or just compromised a local process enough), he/she can use one of the many privilege escalation tool to even automatically put themselves for exam...

While #NixOS should not be affected by #CopyFail as it uses recent kernels, here are additional fixes you can apply:

Disabling setuid does not mitigate it, but reduces the attack surfaces overall significantly.

Instead of #sudo, #su, #pkexec and other #setuid binaries you can use #run0 or a dedicated root account.

I have disabled setuid for a bunch of binaries I don't need, they still work when ran as root, with run0 or #sudo-rs.

```nix
boot.blacklistedKernelModules = [
"algif_aead"
];

security.sudo.enable = false;

security.wrappers = {
su.enable = false;
pkexec.enable = false;

# example setuid binary
chsh = {
source = "${pkgs.shadow}/bin/chsh";
setuid = lib.mkForce false;
owner = "root";
group = "root";
};
};
```

ok guys this is a big one. while testing our infra for the copy fail thing we happened upon another even more severe vulnerability. there is no CVE yet but we expect this to land in the 9.8+ range. it is also a privilege escalation but does not require any python or an internet connection to abuse. why this matters and what you can do to secure your system
