Ah, yes, the "timeless masterpiece" on /dev/urandom from 2014, still bravely clinging to relevance as the Linux kernel evolves faster than the author's ability to admit it. 🙄🤦‍♂️ Pro tip: When your article needs a "note from the future," it's time to rewrite, not recycle. 💾🔄

Linux 7.0.6 and 6.18.29 LTS patch the Dirty Frag local privilege flaw, fixing unsafe rxrpc decryption paths tied to CVE-2026-43500.
Fedora and Pop!_OS shipped fixes before release, reflecting rapid open-source patching and the need for timely user-controlled updates. 🔧

A proposed Linux kernel patch adds a “killswitch” mechanism letting admins disable vulnerable kernel functions at runtime until security fixes are released. 🐧
The patch targets threats like LPE exploits, taints modified kernels with a new flag, and was developed with documented AI-assisted contributions. 🔒

Linux 7.1 RC3 released!

Linux 7.1 RC3 is now live for developers and curious users to try out. All the interesting changes from performance improvements to bug fixes have been integrated to this release candidate.

The official announcement from the kernel mailing list says:

It's Sunday afternoon, and we all know what that means: Mother's Day.

But also your regularly scheduled kernel release candidate.

And I think this answers the "is 7.1 continuing the larger size pattern that we saw with 7.0?" question, and the answer is yes: that wasn't a fluke brought on by a .0 release - it simply seems to be the new normal.

This time around, about a third of the patch is networking - both on the driver side and in core. And related selftests.

The rest is pretty spread out, with other drivers (sound and gpu being the bigger ones, but there's a little bit of everything in there), architecture updates (powerpc and x86, but also some loongarch and parisc), and various other fixes (smb updates, various core kernel updates, Rust infrastructure, selinux, documentation etc).

The shortlog below isn't exactly _short_, but not so long that you can't scroll through it to get some kind of idea of the details.

Why not try out this awesome pre-release of Linux 7.1?

#Linux 7.1-rc3 is now available for public testing from Linus Torvalds's Git tree https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

Linux Weekly Releases (Week 19 – 5/9/2026)

Every week, new Linux versions that are under a supported version series get released to incorporate bug fixes and other general improvements that are pushed to the servicing branches. This ensures that your Linux user experience gets better when latest versions fix some of the bugs.

This week, the below Linux kernel versions under the v7.x series are released:

Alongside v7.x, here are the v6.x versions that were released:

For users who prefer to stay in the v5.x series, here are the latest releases:

Please note that the downloads are in the source code form, so this means that you may have to compile from source in order to use one of the Linux versions shown above. Your distribution might not include the above Linux versions.

Quick reminder in light of the recent #LinuxKernel vulnerabilities:

In case you want to protect yourself against vulnerabilities in #Linux #Kernel modules you don't need, disable module loading completely by running:

echo 1 | sudo tee /proc/sys/kernel/modules_disabled

Of course you want to load all modules you need before running that command, as otherwise you will have to reboot to load them. 😄

Angesichts der jüngsten Lücken im #LinuxKernel kurz der Reminder:

Wenn ihr euch vor Lücken in #Kernel-Modulen von #Linux schützen wollt, die ihr nicht nutzt, könnt ihr das Nachladen untersagen, sobald alle benötigten geladen sind.

Oh, look! Another day, another Linux kernel exploit—because who doesn't love a side of root access with their stack overflow? 🤦‍♂️💻 Apparently, all it takes is a measly u32, and voilà, you're the admin now! 🚀 I guess security's just a suggestion. 🙃
