Linus Torvalds released Linux 7.4-rc1 on November 1, 2026, marking the largest merge window in the kernel's ~35-year history with nearly 20,000 commits. He attributes much of the surge to a flood of AI-generated work, though he also notes 7.4's expected role as next year's LTS kernel is partly responsible. The release packs real features, including Apple M4, AMD Ryzen Zen 6, and Google Tensor G5 support, with the final kernel expected in late December.
Linux 7.2.15 shipped today as the final stable release of the 7.2 series, which Greg Kroah-Hartman retired early so the team can focus on 7.3. The update is tiny at just 15 files but bundles eight real fixes, including a security-critical skb_zerocopy bug that let unprivileged users write to root-owned read-only files. Several of those fixes carry an "Assisted-by: Claude" tag, adding another dated data point to AI-assisted kernel development. Greg says everyone still on 7.2 must upgrade now, though staying on an LTS like 6.18 remains an option.
4MLinux 52.2 STABLE launched on October 31, 2026, bumping its 6.18 LTS kernel to version 6.18.55 as a straightforward point release. Existing 52.x users can upgrade automatically with a single zk update command instead of downloading the roughly 2.3 GB ISO. The independent Polish distro is built entirely from source, runs on x86_64 hardware only, and stays tiny enough to revive ancient PCs and rescue tools alike.
Greg Kroah-Hartman released seven more maintained Linux stable kernel branches today, in a single batch spanning versions 7.2.14 down through 5.10.273. The standard stable-issue work brought no new features but shipped a batch of backported bug fixes and security patches, most notably Christian Brauner's coredump-integrity overhaul, Jens Axboe and Josef Bacik's io_uring remediation, and a keys subsystem patch that hardens keyring indexes against KASLR disclosure. The batch's standout detail is a growing crop of "Assisted-by: Claude," Codex, and DeepSeek sign-off lines in the changelogs, a concrete signal of the AI-assisted development Linus Torvalds has dubbed the kernel's new normal. With the 5.15 and 5.10 long-term lines projected to reach end of life in December 2026, users are again urged to take the full LTS point release and reboot rather than cherry-pick individual fixes.
Linux kernel 7.3.1 shipped today, October 30, 2026, under Greg Kroah-Hartman as the first bugfix point of the 7.3 feature cycle, with 40 commits totaling 39 backported fixes. The headline work covers Christian Brauner's ten-patch series protecting coredump integrity during process teardown, plus a standout security fix that closes a KASLR pointer leak in the keyring subsystem. The release also rounds out io_uring, tracing, Bluetooth, and DAMON patches, and notably includes patches carrying "Assisted-by" credits for AI tools like Claude and DeepSeek. It's a recommended update for anyone on 7.3, though it carries no new features and should avoid the hardware surprises some AMD-GPU users saw with the parent release.
Greg Kroah-Hartman shipped two coordinated stable Linux kernel updates today, tagging 7.2.13 and 6.18.59 within eight minutes of each other. Neither release adds features, but both bundle bug-fix and security patches focused on SMB/CIFS/NTFS data corruption, heap overflows, and use-after-free bugs. The 7.2.13 update rides the newest mainline series, while 6.18.59 is the LTS track supported through at least December 2027. Both deliver overlapping fixes, keeping cutting-edge and production deployments patched on the same schedule.
Offensive Security released Kali Linux 2026.3 today, the third Rolling snapshot of the year, jumping the kernel from 6.19 to 7.1.5. The most substantive change is an overhauled set of build-scripts that lets you containerize and reproduce a trusted official image yourself, though that work only reached its first milestone. On the user side, expect KDE Plasma 6.7, 126 package updates, six new pentesting tools, and NetHunter upgrades that include wardriving from a TicWatch. If you're pulling the image, stick with the official blog for specs, since several third-party recaps are citing stale KDE and kernel versions.
The merge window for Linux 7.4 opened this week, with feature work already landing steadily ahead of a late-December release target. The cycle's standout improvements include a boot-time memory operation that drops from roughly 268 seconds to 50 milliseconds, workqueue flushing that speeds up by orders of magnitude, and a long-awaited cleanup removing the unsafe __get_user() and __put_user() helpers. Rust also took a small but symbolic step forward by replacing and deleting Google's C-language Binder driver rather than merely running alongside it. Timing remains the main risk, since Torvalds spent the initial merge window on his annual vacation and the stable release could slip into mid-January 2027.
The Linux kernel project is finalizing four stable releases this week, 7.2.12, 6.18.58, 6.12.114, and 6.6.160, each on a different maintenance track from newest mainline to oldest LTS. All four inherit the fix for CVE-2026-99999, a critical guest-to-host VM escape nicknamed "PwnEscape" that dated back to Linux 2.6.27. Patch volume is staggering, with 6.6.160 carrying 1,674 fixes after nearly three years of backporting while the fresh 7.2.12 needs just 10. Linus Torvalds calls this volume "the new normal," driven by AI-assisted review, and operators' best move is simply to update to the newest point release for their branch and reboot.
The Free Software Foundation Latin America has released GNU Linux-libre 7.3-gnu, a 100% free rebuild of the just-upstream Linux 7.3 kernel that landed one day earlier. Its main job was clearing proprietary binary blobs out of drivers like the Tyr Mali GPU, Morse Micro and NXP Wi-Fi, plus a longer list of pre-existing graphics and network components. Freedom comes at a cost: some sound, video, and especially Wi-Fi and hardware won't work, and the kernel doesn't push CPU microcode updates tied to security fixes. It's available via git, tarballs, or compiled .deb and .rpm packages for anyone building a fully auditable GNU/Linux system.
Linux kernel 7.3 shipped today, marking the fifth major release of the 7.x era. With 15,267 commits, it logged the second busiest merge window ever behind Linux 6.7, pushing the kernel to roughly 40.98 million lines of code. Torvalds credits AI and LLM coding agents for both the growth and the accelerating removal of stale drivers. The update brings AMD Zen 6 prep, faster Btrfs, stable Intel Nova Lake integrated graphics, and new controller support, as maintainers weigh whether 7.3 or 7.4 takes this year's LTS crown.
Greg Kroah-Hartman signed off on four LTS kernels, 6.6.159, 6.1.190, 5.15.223 and 5.10.272, each carrying the same small set of backported networking and security fixes. The updates close a TCP use-after-free, harden IPv4 checksum validation and restore SCTP traffic through nfnetlink_queue, clearing the thresholds of Canadian advisory AV26-970. Two of the branches, 5.10 and 5.15, sit just two months from end of life on December 31, 2026, intensifying migration pressure for Ubuntu 22.04 and RHEL 9 users. The other two, 6.1 and 6.6, remain safe through the end of 2027, making this a planning window rather than a panic.
Three Linux kernel point releases, 7.2.11, 6.18.57, and 6.12.113, has been released today, within minutes of each other and signed off by Greg Kroah-Hartman. All three carry the same shared fixes for the Steam controller driver, sched_ext, AMD display, and the CAN subsystem, but each branch also brings its own standout patches. The newest LTS (6.18.57) leads with a fix for the XFS "refluxfs" data-corruption bug and s390 zcrypt memory-disclosure hardening, while 6.12.113 includes a netfilter fix that stops OpenWrt routers from dropping WiFi after ~300 seconds. The updates also carry "Assisted-by: Claude" tags, underscoring how AI-assisted review has become routine, and the advice is the same as always: patch the branch you run and reboot.
Linus Torvalds released Linux 7.3-rc7 on Sunday, admitting it arrived about six hours late because he mixed up the day after traveling to the Kernel Maintainer Summit and Linux Plumbers Conference. It's a fixes-only snapshot that leans heavily on VFS maintainer Christian Brauner's mount-namespace hardening, credited with 58 entries. The cycle also deprecates ext4's data=journal mode for removal in 2028 and pulls in an AMD TLBI Erratum #1718 workaround. Stable Linux 7.3 is still on track for next weekend, around 18 October 2026.
Greg Kroah-Hartman shipped two stable Linux kernels on the same day: 7.2.10 for the current mainline series and 6.18.56 for this year's LTS release. Both carry the same headline fixes, most importantly a TCP IPv4 use-after-free squashed by Eric Dumazet and a KASLR leak closed through the perf subsystem. Virtualization got heavy emphasis too, with a cluster of KVM/x86 nested-virt memory-safety patches plus an ARM Cortex-A725 erratum workaround shared across both trees.
Linus Torvalds shipped the sixth release candidate for Linux Kernel 7.3. The release brings 524 commits from 281 contributors, including roughly 69 memory-safety and security-relevant patches even though no CVE was announced. The heaviest lifting came from Sean Christopherson's 21 KVM commits, with supporting work from Johan Hovold on USB-serial teardown races and Paulo Alcantara's SMB/netfs data-integrity fixes.
The Linux kernel project just shipped seven stable releases in under twenty minutes, all landing today. Greg Kroah-Hartman signed off on 7.2.9 down to 5.10.271, a batch spanning the newest 7.x line all the way back to the oldest still-supported 5.10 LTS tree. Memory-safety fixes dominate the changelog, with use-after-free and out-of-bounds bugs found largely by fuzzers like syzbot and AI-assisted tooling. All seven are live now at kernel.org, so distro security updates should roll out over the coming days.
4MLinux 53.0 BETA launched as a full desktop-and-miniserver image rather than a half-built prototype. It rides on a modern core built from source with what the project calls "a huge number of updated packages." The Polish distro sidesteps traditional package managers, delivering software as self-contained addons and rebuilding its tiny core on boot to stay comfortably light on old hardware. It is one step toward a November STABLE release, with old-stable support through March 2027 and end of life in July.
Linux Kernel 7.3-rc5 has landed as the fifth release candidate of the 7.3 cycle, bringing 577 commits from 275 contributors. Linus Torvalds flagged an atypical diffstat where drivers make up less than a third and selftests claim roughly a quarter, though he attributes this to small driver patches and a few large test files rather than anything substantive. Networking and KVM architecture work dominate the tree, with around 101 commits touching memory-safety or concurrency concerns consistent with a normal release candidate.
Two Linux kernels have been released today. Kernel 7.2.8 bringing roughly 438 commits and LTS 6.18.54 around 397. Both are bug-fix and security backports led by Greg Kroah-Hartman, with the latest 6.18.54 supported until December 2028. The biggest changes target SMB/CIFS networking hardening, AMD GPU and IPsec fixes, and improved wireless and filesystem reliability.
