The GNU Privacy Guard (GPG) project decided to break from the OpenPGP standard for email encryption in 2023, and instead adopted its own homegrown LibrePGP specification. The GPG 2.4 branch, the last one to adhere to OpenPGP, will be reaching the end of life in mid-2026. The Fedora project is currently having a discussion about how that affects the distribution, its users, and what to offer once 2.4 is no longer receiving updates.
Curl creator Daniel Stenberg has written a blog post explaining why the project is ending its bug-bounty program, which started in April 2019:
The never-ending slop submissions take a serious mental toll to manage and sometimes also a long time to debunk. Time and energy that is completely wasted while also hampering our will to live.
I have also started to get the feeling that a lot of the security reporters submit reports with a bad faith attitude. These "helpers" try too hard to twist whatever they find into something horribly bad and a critical vulnerability, but they rarely actively contribute to actually improve curl. They can go to extreme efforts to argue and insist on their specific current finding, but not to write a fix or work with the team on improving curl long-term etc. I don't think we need more of that.
There are these three bad trends combined that makes us take this step: the mind-numbing AI slop, humans doing worse than ever and the apparent will to poke holes rather than to help.
Stenberg writes that he still expects "the best and our most
valued security reporters
" to continue informing the project when
security vulnerabilities are discovered. The program will officially
end on January 31, 2026.
So normally this would be the last rc of the release, but as I've mentioned every rc (because I really want people to be aware and be able to plan for things) this release we'll have an rc8 due to the holiday season.And while some of the early rc's were smaller than usual and it didn't seem necessary, right now I'm quite happy I made that call. Not because there's anything particularly scary here - the release seems to be going fairly smoothly - but because this rc7 really is larger than things normally are and should be at this point.
Along with the usual fixes, this -rc also includes a new document describing the process to replace the kernel project leadership should that become necessary in the absence of an arranged transition. The plan largely follows what was decided at the Maintainers Summit in December.
Version 1.5.0 of the GNU Guix package manager and the Guix System have been released. Notable improvements include the ability to run the Guix daemon without root privileges, support for 64-bit RISC-V, and experimental support for the GNU Hurd kernel.
The release comes with ISO-9660 installation images, virtual machine images, and with tarballs to install the package manager on top of your GNU/Linux distro, either from source or from binaries—check out the download page. Guix users can update by running guix pull.
It's been 3 years since the previous release. That's a lot of time, reflecting both the fact that, as a rolling release, users continuously get new features and update by running guix pull; but it also shows a lack of processes, something that we had to address before another release could be made.
During that time, Guix received about 71,338 commits by 744 people, which include many new features.
LWN last looked at Guix in February 2024.
The Linux Kernel Runtime Guard (LKRG) is a out-of-tree loadable kernel module that attempts to detect and report violations of the kernel's internal invariants, such as might be caused by an in-progress security exploit or a rootkit. LKRG has been experimental since its initial release in 2018. In September 2025, the project announced the 1.0 version. With the promises of stability that version brings, users might want more information to decide whether to include it in their kernel.
ReactOS, an open-source project to develop an operating system that is compatible with Microsoft Windows NT applications and drivers, is celebrating 30 years since the first commit to its source tree. In that time there have been more than 88,000 commits from 301 contributors, for a total of 14,929,578 lines of code. There is, of course, much left to do.
It's been such a long journey that many of our contributors today, including myself, were not alive during this event. Yet our mission to deliver "your favorite Windows apps and drivers in an open-source environment you can trust" continues to bring people together. [...]
We're continuing to move ReactOS forward. Behind the scenes there are several out-of-tree projects in development. Some of these exciting projects include a new build environment for developers (RosBE), a new NTFS driver, a new ATA driver, multi-processor (SMP) support, support for class 3 UEFI systems, kernel and usermode address space layout randomization (ASLR), and support for modern GPU drivers built on WDDM.
Version 3.0.0 of the pandas data analysis and manipulation library for Python has been released. Notable changes include a dedicated string type (str), new "copy-on-write" behavior, and much more. This release also removes a number of features that were deprecated in prior versions of pandas; developers are advised to upgrade to pandas 2.3 and ensure code is working without warnings before moving to 3.0. See the release notes for the full changelog.
At the 39th Chaos Communication Congress (39C3) in December, researchers Lexi Groves ("49016") and Liam Wachter said that they had discovered a number of flaws in popular implementations of OpenPGP email-encryption standard. They also released an accompanying web site, gpg.fail, with descriptions of the discoveries. Most of those presented were found in GNU Privacy Guard (GPG), though the pair also discussed problems in age, Minisign, Sequoia, and the OpenPGP standard (RFC 9580) itself. The discoveries have spurred some interesting discussions and as well as responses from GPG and Sequoia developers.
We cannot fix email delivery, but we can sidestep it entirely. Public-inbox archives like lore.kernel.org store all mailing list traffic in git repositories. In its simplest configuration, korgalore can shallow-clone these repositories directly and upload any new messages straight to your mailbox using the provider's API.
The telnetd server invokes /usr/bin/login (normally running as root) passing the value of the USER environment variable received from the client as the last parameter.If the client supplies a carefully crafted USER environment value being the string "-f root", and passes the telnet(1) -a or --login parameter to send this USER environment to the server, the client will be automatically logged in as root bypassing normal authentication processes.
