Linux Kernel 6.18 was released yesterday! According to the version history, it will be probably the next Long Term Support (LTS) kernel release.
Linus Torvalds announced this kernel release on this lkml.org page:
So I’ll have to admit that I’d have been happier with slightly less bugfixing noise in this last week of the release, but while there’s a few more fixes than I would hope for, there was nothing that made me feel like this needs more time to cook. So 6.18 is tagged and pushed out.

On CPU side, the new kernel updated Intel Trust Domain Extensions (TDX) to work with Kexec for being able to load and boot into a new kernel from another currently running kernel. It updated FRED with patch for the late breaking incompatible change. And, it added a workaround for Xeon 6 to avoid performance issue.
For AMD, it updated Error Detection And Correction “EDAC” driver with next Zen 6 “Venice” server processors support. And, added patch for the old Bulldozer processors with X86_NATIVE_CPU option support for maximizing performance.

The Kernel also added support for Sheaves, a new opt-in, per-CPU and array-based caching layer, updated IOMMU driver with ACPI and MIPS vendor extensions support for RISC-V, and introduced Loongson Security Engine support for handling offloaded RNG, TPM2, and various crypto acceleration on LoongArch processors.
It as well added patch to reliably handle 255+ vCores on AMD EPYC servers, enabled Wildcat Lake graphics support, introduced new Rocket accelerator driver for the NPU found on newer Rockchip SoCs, and added Google’s PSP encryption for TCP connections.
The Bcachefs code is removed from Kernel 6.18, users should now use DKMS kernel modules instead. And, exFAT file-system driver has been optimized leads to 16.5x speedup for loading time.
The new Kernel also added many new hardware support. They include:
For more about Linux Kernel 6.18, see either kernelnewbies.org or phoronix.com pages.
The Mainline Kernel PPA has built the new kernel as .deb packages, which are available to download through the link below:
Depends on your CPU architecture type (run uname -a or dpkg --print-architecture command to tell), select download either amd64 for Intel/AMD, armhf/arm64 for 32-bit/64-bit ARM, or ppc64el for IBM POWER, s390x for IBMz or LinuxONE.
NOTE: the Mainline Kernel packages are NOT signed! You need to disable secure-boot to boot the kernel. And it may be not work properly with NVIDIA proprietary driver.
For Intel/AMD platform, you may open terminal or connect to the server console, then run the commands below one by one to download & install the Kernel:
cd /tmp wget -c https://kernel.ubuntu.com/mainline/v6.18/amd64/linux-headers-6.18.0-061800-generic_6.18.0-061800.202511302339_amd64.deb wget -c https://kernel.ubuntu.com/mainline/v6.18/amd64/linux-headers-6.18.0-061800_6.18.0-061800.202511302339_all.deb wget -c https://kernel.ubuntu.com/mainline/v6.18/amd64/linux-image-unsigned-6.18.0-061800-generic_6.18.0-061800.202511302339_amd64.deb wget -c https://kernel.ubuntu.com/mainline/v6.18/amd64/linux-modules-6.18.0-061800-generic_6.18.0-061800.202511302339_amd64.deb sudo apt install ./linux*-6.18.0*.deb
After installed the packages, restart your computer or server and run uname -a to verify.
For any reason, you may remove this Kernel by firstly rebooting into the old Kernel (usually under Grub -> Advanced options of Ubuntu)., then run command:
sudo apt remove --autoremove linux-headers-6.18.0* linux-modules-6.18.0-*-generic
Linux kernel 6.18 is now available for download with new features, enhanced hardware support through new and updated drivers, improvements to filesystems and networking, and much more. Here’s what’s new!

Linux 6.17 is out as the latest Kernel release! Linus Torvalds announced it yesterday afternoon in lkml.org:
No huge surprises this past week, so here we are, with kernel 6.17 pushed out and ready to go.
Below is the shortlog for just the last week – not the full 6.17 release – as usual. It’s not exciting, which is all good. I think the biggest patch in there is some locking fixes for some bluetooth races that could cause use-after-free situations. Whee – that’s about as exciting as it gets.
…
Linux 6.17 introduced Attack Vector Controls, which provides a simple method to manage CPU vulnerability mitigations. Which, so far supports 5 sets of attack-vector mitigations: User-to-Kernel, User-to-User, Guest-to-Host, Guest-to-Guest, and Cross-Tread. See the official documentation for more about it.
For Intel, the kernel added Intel IPU7 driver for web camera support on Lunar Lake and Panther Lake laptops. And, it added perf profiling support for Panther Lake, and EDAC (Error Detection and Correction) support for Granite Rapids D, Wildcat Lake, and Raptor Lake HX, and Core i5 14600, i7 14700 processors.
It as well added initial support for Wildcat Lake integrated graphics, enabled OpenGL and Vulkan support for Xe3 Panther Lake graphics by default, and added SR-IOV (Single Root I/O Virtualization) support for Battlemage GPUs but limit to Arc Pro graphics card.
There are as well DRM Panic support for the Intel i915 and Xe kernel drivers, Wildcat Lake “WCL” display enablement, and experimental flip queue support for Lunar Lake and Panther Lake hardware, and NPU accelerator support for Wildcat Lake.

On the AMD side, the kernel merged AMD’s Hardware Feedback Interface driver for dynamic core ranking, improved task scheduling, and better support for processors with mix of classic and dense cores.
It also added SmartMux support for hybrid laptops that dynamically switch the GPU being used. For example, when gaming, the system can be switch the active display to the discrete GPU for better performance.
Other AMD changes include CPUID faulting support, and fix for AMDGPU hibernation, which can save 50 minutes on large GPU servers.

Other changes in this Kernel release include:
There are as well many new and updated hardware support, including:
For more changes about Linux Kernel 6.17, see either this page or kernelnewbies.
Ubuntu 25.10 has already included Kernel 6.17 RC, while the stable release will be available soon in the final release.
For Ubuntu 24.04, it will probably have Kernel 6.17 in next 24.04.4 point release. If you can’t wait, try the mainline kernel PPA.
NOTE: The mainline Kernel is built for testing purpose! It’s NOT signed, so you need to disable secure boot for being able to boot the kernel. And, it may have compatibility issues with proprietary drivers.
For amd64, arm64, armhf, ppc64el, and s390x CPU architecture types, the Kernel PPA provides Linux Kernel 6.17 package at the link below:
If you don’t know your CPU type, run dpkg --print-architecture command to tell, then select download & install the proper packages for your system.
For modern Intel/AMD (amd64) platform, open terminal (Ctrl+Alt+T) and run the commands below one by one to download & install the kernel:
wget -c https://kernel.ubuntu.com/mainline/v6.17/amd64/linux-headers-6.17.0-061700-generic_6.17.0-061700.202509282239_amd64.deb wget -c https://kernel.ubuntu.com/mainline/v6.17/amd64/linux-headers-6.17.0-061700_6.17.0-061700.202509282239_all.deb wget -c https://kernel.ubuntu.com/mainline/v6.17/amd64/linux-image-unsigned-6.17.0-061700-generic_6.17.0-061700.202509282239_amd64.deb wget -c https://kernel.ubuntu.com/mainline/v6.17/amd64/linux-modules-6.17.0-061700-generic_6.17.0-061700.202509282239_amd64.deb sudo apt install ./linux-headers-6.17.0*.deb ./linux-image-unsigned-6.17.0*.deb ./linux-modules-6.17.0*.deb
After installed the kernel, restart and run uname -a to verify the new kernel.
To remove the kernel 6.17, reboot and select boot an old kernel entry from Grub boot-loader (usually under Advanced menu), then run the command below to uninstall:
sudo apt remove linux-modules-6.17.0-*-generic linux-headers-6.17.0-061700
