From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Important: Nobara is way less Secure than Fedora.

  • no Secureboot
  • monthly updates instead of often daily
  • purposefully removed SELinux (because the Dev doesnt know how to use it)
  • still no Fedora39!

If you want to game, stick to regular Fedora. A project that is actually secure is ublue with dedicated NVIDIA images that should just work and never break, and they even have Bazzite, an Image specifically for the Steamdeck but also for Desktop.

These images are only ½ day behind upstream, apply minimal additions and patches (like drivers, codecs, packages, udev rules for controllers) and Nick from the video above found out that the Nobara patches with their weird less supported Kernel arent really worth the hassle.

Secure Boot is an utter piece of bullshit from the depths of hell.

Proprietary UEFI BIOS is, but for a secure system with local manipulation prevention it can be needed. Also secureboot is a security measurement against malware so no, its simply the best we have.

Look at Coreboot if you want a secure modern system

  • novacustom
  • 3mdeb
  • starlabs
  • system76

Secure Boot is just Bootloader Signature Enforcement controlled by M$, it's not gonna prevent Superfish 2.0 from happening.

Unfortunately, I don't have a coreboot-able system. When I move out I'll make that a priority.

I never bought my current machines. Funnily enough, they don't show any logos on bootup, (Windows Boot Manager is smth else)

The vulnerability actually isn’t in Windows Boot Manager, it’s a flaw in the image-parsing code of the UEFI itself. That’s why it’s able to bypass SecureBoot.

It just happens that for whatever reason you can easily update the image file from within Windows/Linux itself. The fact they don’t show a logo currently does not mean you’re immune, as the system might just be showing a black screen at that point. Code can be injected into an image file without perceptibly affecting the image output, so you’d likely be able to use a “black screen” logo. If your computer has a UEFI instead of a BIOS, which is pretty much everything from the last 10yrs, then you are more than likely at risk.

My computer likely isn’t susceptible, and that’s because it’s a Dell workstation. While the bug still exists in the image parser, Dell has locked things down so it’s pretty much impossible to change the boot logo from userspace.

Yes, IK WBM is not the problem here. My systems don't show a logo at all, and they don't have a "hide logo" options.

FWIW, some firmware allow changing it during the update procedure. I remember having to update my ThinkPad's firmware and it had that option.

[–] [email protected] 1 points 11 months ago

That’s valid, I looked into it with Dell and later articles have mentioned they aren’t susceptible.
