Dirty Frag: Universal Linux LPE https://www.openwall.com/lists/oss-security/2026/05/07/8

This is a report on "Dirty Frag", a universal LPE that allows obtaining root privileges on all major distributions. This vulnerability has a similar impact to the previous Copy Fail.

#linux #security

Oh good, another high-severity #Linux #security vulnerability that somebody botched the disclosure of, turning it into a high-severity zero-day.

Because #CopyFail wasn't bad enough. Now we've got #DirtyFrag too.

Can #cybersecurity people please stop botching vulnerability disclosure? Thanks.

“My favorite device is a Chromebook, without ChromeOS”

If you're sick of Chrome OS on your Chromebook, or can find a Chromebook for cheap somewhere but don't actually want to use Chrome OS, have you considered postmarketOS?

Since I was kind frustrated with ChromeOS, I decided to take a look at something that I knew supported my Lenovo Duet 3 for some time: postmarketOS. For thos

“Works on my laptop” is a configuration problem, not bad luck.

Execution Environments make your Ansible control node a versioned, reproducible container image. Same artifact locally, in CI, and in AAP/AWX.

I wrote a practical walkthrough of ansible-builder + ansible-navigator, with real-world gotchas:

cp -prva ~/gate/secret/files* /media/my_user_id/gate/public/deep/dive

works in the following sh:

• ksh
• csh
• zsh
• tcsh
• dash
• ash
• psh

hey so. looking for a job (NZ or fully remote willing to hire a kiwi) in SRE, security, or linux/Unix system administration. 15 years experience administering Linux and Unix boxes, intermediate level of experience working with docker compose and containerisation and container security. No prior job experience unfortunately, all those 15 years were mostly personal projects and small-scale stuff for friends. I'm also 26, so I started when I was 11, explaining the no jobs so far. Currently running an entire multi-machine personal cloud infrastructure with a demonstration of all the services I have running at https://status.highenergymagic.net. Three machines, 72 docker containers. One running most of them, one running Mastodon+glitchsocial, one running the uptime monitor. encrypted root on ZFS, alpine linux, gVisor on supported containers, plan to move to Kata. Entirely willing to accept entry-level job placements, no expectation of being paid a lot or anything, just want to be doing something and move the needle a little on my current "being broke" status. Currently using gVisor, docker compose, and kata containers in production, experience with Linux, docker, Net/Open/FreeBSD, Cisco IOS, Juniper Junos, Mikrotik and UniFi, configuring and administering Asterisk, plus extensive experience with IBM AIX and Sun Solaris. #fedihired #infosec #cybersecurity #linux #unix #docker #sre #DevOps #GetFediHired

Please boost for reach, any job offers please DM me.

I"m leaning towards #dnsmasq

what do you #Linux folks use as a stupid simple DHCP server daemon? #Kea seems a bit overkill for what I need, and isc-dhcpd is effectively unmaintained.

$ sudo resolvctl status is taking forever.

I really, really, really wish #Linux would implement SIGINFO.

Today I came across a weird #printer problem. From #Debian #Linux I could print to the #Canon PIXMA printer in simplex or #duplex.

BUT, in duplex mode it would print a side, eject the paper, re-load the paper, then eject it again without printing anything on it, and then start the second page on a separate sheet of paper.

This happened from my PC and a separate one using the stock #IPP driver in #CUPS

Annoyingly it works perfectly in Windows...

Your nightly reminder that the bugs are Long Term Stable too and the maintainers of those projects can't fix your distro.

Recently I got asked about my @BoxyBSD@bsd.cafe project, which offers free VPS instances of vary #BSD based systems for learning and educational purposes and I'm happy to share that this projects remains available. Several things could finally be clarified to continue this service to make sure people can learn and practice on real #FreeBSD, #OpenBSD, #NetBSD systems to #RUNBSD. Also, BoxyBSD starts moving over to #Sylve on #bhyve.

But not only that! We could also get some more new resources and locations to scale and this also brings up another new project for #free Linux #VPS instances at https://boxedtux.com (Fedi: @BoxedTux@mastodon.social) where people will be able to learn and practice on different #Linux based distributions (e.g., #Debian, #Ubuntu, #Rocky,...). BoxedTux utilizes #Proxmox clusters as a foundation.

Hope you like this small update... Over & out!

How to Install OpenBSD (2027 Edition)

Gkrellm is one of the lightest system monitoring tools that I use, only top and htop are lighter. Of course it's a Natural Choice on not only the SBC Pi5 but on all machines here

On these displays you see the SBC in action. The screen on the lower right belongs to a very old sturdy notebook which couldn't even run an important piece of OpenSource software I use to make certain types of connections. I had to degrade The Notebook to a music player after I got it out the two and a half inch hard drive
