14 DAY TRIAL // As promised, Linux kernel maintainer Greg Kroah-Hartman released today new versions of the Linux 4.14, 4.9, and 4.4 kernel series to address some of the regressions from previous builds and fix more bugs.
Linux kernels 4.14.13, 4.9.76 LTS, and 4.4.111 LTS are now available for download from kernel.org, and they include more fixes against the Spectre security vulnerability, as well as some regressions from the Linux 4.14.12, 4.9.75 LTS, and 4.4.110 LTS kernels released last week, as some reported minor issues.
These issues appear to be fixed now, so it's safe to update your Linux-based operating systems to the new kernel versions released today, which include more x86 updates, some PA-RISC, s390, and PowerPC (PPC) fixes, various improvements to drivers (Intel i915, crypto, IOMMU, MTD), and the usual mm and core kernel changes.
"I'm announcing the release of the 4.14.13 [4.9.76 and 4.4.111] kernel. All users of the 4.14 [4.9 and 4.4] kernel series must upgrade. The updated 4.14.y [4.9.y and 4.4.y] git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.14.y, git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.9.y, and git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.4.y," said Greg Kroah-Hartman.
More kernel updates are coming soon to mitigate Spectre
As Greg Kroah-Hartman said a few days ago in a lengthy blog post regarding the status of the Meltdown and Spectre security exploits on the Linux kernel, more such kernel updates will be available in the coming weeks and months, so you need to make sure you update your distributions as soon they are released.
Therefore, go ahead and update your Linux boxes to the Linux 4.14.13, 4.9.76 LTS or 4.4.111 LTS kernels either by downloading the source archives and compile them for your hardware architecture, or installing them from the stable software repositories of your favorite GNU/Linux distribution.
