Falling apart? You mean getting stronger? Every single one of these is an existing hole being patched. It isn't making new holes

Government agencies probably already have half of these exploits in their private toolbox for years now. Finding and patching them is good, but there probably needs to be some systematic change to prevent them rather than just patching bugs when they get found.

Something something microkernels + capability-based security.

The thing is you can actually write quite good C code (see OpenBSD project). The power of C is that it's pragmatic. It lets you write code with you taking the full responsibility of being a responsible person. To err is human, but we developed a set of practices to handle this (by making sure the gun is unloaded and the safety is on before storing it to avoid putting holes in feet). I like type checking and other com…

> To err is human Yes, which is precisely why I write in Rust, because the compiler errs less than I do.

It may, but it still requires careful annotations. So you should hope that you have not made an error there and described the wrong structure for the code.

Desktop and server vulnerabilities are one thing. At least many are actively maintained and will get patched. I have a concern about all the common and cheap internet firewalls and routers that are around, running old software and kernels. Many or most will not get patched. I have some Ubiquiti boxes that are long out of support and run old kernels for instance. The hope is only that there's nothing they expose that gets hit.

Another one. Linux is falling apart faster than it can assign these CVEs.

As other people said in this thread: so many devices won't be patched. And that can easily lead to users and manufacturers moving away from Linux. Linux is in a glass house.

Let's see... That's 4 Linux LPEs in the last 10 days? Copy Fail [1] Copy Fail 2: Electric Boogaloo [2] Dirty Frag [3] And now this... [1]: https://copy.fail [2]: https://github.com/0xdeadbeefnetwork/Copy_Fail2-Electric_Boo... [3]: https://github.com/V4bel/dirtyfrag

Aren't CF2 and DF the same exploit?

Automated vulnerability discovery via LLM.

Everyone was talking about how Mythos was overblown marketing, and while it may be, they missed the forest for the trees. Capabilities have been escalating for a year now and we're at the point of widespread impact. I don't suspect we'll see a slowdown for a long time.

Same applies to them being good enough to program, but many are so focused on source code generation that they don't get the whole picture.

Thanks to agents and tool calling, there are now business cases that can be fully described by AI tooling, the next step in microservices, serverless and what not.

Naturally with a much smaller team than what was required previously.

high privilege access required (CAP/NET admin), containers / sandboxing wins once again. Can we make sandboxing the new default now? Flatpak does a good job, but we're still pretty far away for apt/yum/pacman installed packages. AppArmor was a decent step forward, but clearly not enough.

Yes on Android, iDevices, macOS, Windows (UWP, Win32 boxing), Qube OS, but it remains a controversial topic in GNU/Linux land.

I remember when people used to joke with Windows security and something like that would never happen on Linux, well..

perhaps this will lead to better AppArmor and SELinux defaults?

People will just turn SELinux off rather than have to go through the horrible tooling when it breaks a regular use case.

It is enabled by default on Android, and only developers can change it temporarly via an ADB session.
