Greg Kroah-Hartman has announced the release of the 7.1.3 , 6.18.38 , 6.12.95 , 6.6.144 , 6.1.177 , 5.15.211 , and 5.10.260 stable kernels. Several kernels in this batch include a fix for a vulnerability introduced in the 6.0 kernel in IPv6 ( CVE-2026-53362 ), which could allow an attacker to escape a container and gain root access . There is also a fix for a use-after-free bug in KVM ( CVE-2026-53359 ) that was introduced in the 2.6.36 kernel. As usual, each stable kernel includes a number of …

The GNU Guix project has announced three vulnerabilities in the guix substitute utility as well as a fourth that affects the guix pull and guix time-machine commands. The impact of the vulnerabilities ranges from remote privilege escalation to local disclosure of sensitive files. The remote exploitation of guix substitute only requires that the vulnerable system attempt to download a binary substitute. Any configured substitute server, including ones discovered using guix-daemon 's --discover o…

A number of problems related to negative directory entries (dentries) were the topic of a filesystem-track session at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit . Negative dentries are used to indicate that a file of a given name does not exist in a directory; it is an optimization that short-circuits the lookup of the file name when the answer is already known. Miklos Szeredi led a session that discussed some problems that come from having too many negative dentries …

In August 2025, the CalyxOS privacy-focused Android distribution announced that it was pausing all releases while it reworked its release process, security protocols, and changed its signing keys following the departure of one of its founders. The project has now announced that it is " officially back from the hiatus " with the 7.2.2.0 release. CalyxOS 7.2.2.0 is signed by us using a new HSM-based, open-source signing solution we designed to enhance the security of the entire signing process, e…

A few astute observers have noticed that some content on kernel.org had disappeared and were understandably concerned. Konstantin Ryabitsev has provided an update via social.kernel.org: There was an unfortunate error while changing the kernel.org primary/secondary mirroring infrastructure, which resulted in the /pub tree suddenly becoming empty. No data was lost, just public mirror copies. Everything is now being restored, but deletes are fast and restores are slow, so thank you for your patien…

We were made aware today of an email sent to a reader that was spoofed to appear to be from LWN. The message claimed, among other things, that we were providing personal information about the reader to another site user. As is explained in our privacy policy we do not, and would not, provide such information. If any other readers have received an odd message from LWN, it is an attempt at a hoax; if in doubt, please check the DKIM header of the email. Any email that does come from LWN will have …

Aoife Moloney has, on behalf of the Fedora Council , posted an announcement that the Fedora Council is " proposing we pause the Community Initiatives process as an official project process " because it has decided the current process is ineffective. It is also closing discussion regarding the AI developer desktop initiative covered by LWN in May. The Fedora Objectives/Initiatives framework was never intended as a mandatory prerequisite to do the work in Fedora. It supposed to help by focusing t…

The kernel community (like many other free-software projects) has recently seen a large influx of patches developed with the assistance of large language models (LLMs). Those patches tend to come from developers who were previously unknown to the community. At the moment, though, the memory-management developers are evaluating two large patch sets, developed with LLM assistance, that were submitted by established and well-respected developers. The rather different reception accorded to that wor…

When a BPF program is used to filter or redirect packets in the networking subsystem, the program will often want to associate data with each packet as it moves through the kernel. The kernel's local BPF storage API , which associates extra data with some kernel objects, provides a way to do that. (See also the BPF map types that end in STORAGE .) Amery Hung and Jakub Sitnicki led two sessions at the 2026 Linux Storage, Filesystem, Memory-Management, and BPF Summit about how to make accesses to…

Linux users who have Secure Boot enabled on their systems rely on certificates issued by Microsoft to verify the software used to boot a system is trusted by the user. One of those certificates expired recently, but that will not cause systems that are able to boot to stop doing so. There are situations where the expiration may cause problems, however, and the window for relying on existing signed binaries is shorter than it might appear. Users and administrators will want to stay on top of the…

Dee Harris has published a summary of the recent "fireside chat" featuring Creative Commons founders Hal Abelson, Lawrence (Larry) Lessig, Molly Van Houweling, and Glenn Otis Brown. The chat was to mark the 25th anniversary of Creative Commons and included a look back at its history as well as a look at the landscape today: Twenty-five years ago, a small group of people made a bet. They believed that if you gave creators a simple set of tools and licenses in language that a lawyer, a machine, a…
