  1. A new pull request has been opened at github.com/freebsd/drm-kmod/pu to include a #virtio driver in the #FreeBSD #DRM/#KMS graphics stack.

    That is great news for all those who are using FreeBSD as a desktop system as a VM because this will finally allow using e.g. #Wayland or accelerated #X11.

  2. I really enjoy projects with good documentation. A wonderful rabbithole. And of course nushell and rio-terminal are available on FreeBSD, and included in my upcoming Hyprland config 🥳

  3. FreeBSD: kernel use-after-free via tty ioctls – CVE-2026-58093

    cve.org/CVERecord?id=CVE-2026-

    "The TIOCSCTTY ioctl handler drops the tty lock in order to acquire the process tree lock. After reacquiring the tty lock, the handler did not revalidate the state of the terminal, and could proceed to link a terminal that was concurrently being destroyed to the calling process' session. An unprivileged local user can exploit this race condition to escalate privileges."

  4. The bear is friendly. Think of honey, if you can.

    For anyone who wonders why tags included #FreeBSD, it's because – in addition to the write-up of CVE-2026-58083 and CVE-2026-58084 (July 2026) – I assume that Hazley Samsudin might also choose Blimpers for CVE-2026-58092 (August).

  5. A lot was read, some was learned and some was just copied, because it was worthwhile. My Codeberg page with the FreeBSD 15 Base install has been updated already; blog and Hyperio to follow!

  6. Gladius, that previously crashed on Ghostbsd, now works perfectly with Vulkan that works correctly.

    Noted on Kubuntu 26.04 in Microsoft Edge 152.0.4191.41, Firefox 154.0.1, NetSurf 3.11. No problem in lynx 2.9.2-2. I can't test some of the other installed browsers.

    bokut.in/freebsd-patch-level-t is bugged in lynx.

  8. @intro 🐧freebsd: Mehr 🇩🇰 wagen 💪 Ah, I see. I mixed up OpenBSD and FreeBSD 🙄

    I can hear my former colleague @✰ 𝔽𝕣𝕖𝕕 ✰ roll his eyes at me now 😄

    Sorry, I don't do it on purpose... 🤷

    I always do the same with Star Wars and Star Trek.

    Although that is on purpose, if I can help it 😇

  10. I'd never expect to have that much fun configging a terminal. I mean, aside from a new fastfetch config that is 🤣 Both on FreeBSD, in my Hyprland config.
