How to check if Zenbleed mitigation(chicken bit) is properly set?
  • I thought that was only for Eypc processors with desktop processor fixes coming later this year. The articles are not very clear with what is fixed when.

    How to check if Zenbleed mitigation(chicken bit) is properly set?
  • Thanks, it works. That's a bit worrying.

    Do you think Ubuntu 22.04 will get the security update soon? I got a microcode update today but i think that's only a fix for server cpus and not desktop cpus.

    For anyone having permission problems turn off secure boot in order for this to work.

  • I'm a newb and ran the recommended mitigation code to set a chicken bit on my processor. After running it there was no indication that it worked. Is there a simple way to use rdmsr to check?

    Any open source alternatives for Jerboa? Lemmur seems broken - tells me Lemmy.one doesn't exist.
  • Jerboa is made by Lemmy's developers, and is free, open-source software, meaning no advertising, monetizing, or venture capital, ever. Your donations directly support full-time development of the project.

    I guess they want a different open source client.
