A nasty vulnerability has been made public today concerning Glibc's dynamic loader that can lead to full root privileges being obtained by local users. This affects Linux distributions of the past two years with the likes of Ubuntu 22.04 LTS, 23.04, Fedora 38, and others vulnerable to this local privilege escalation issue...

The biggest hindrance for using Intel Arc Graphics for Linux gaming has been the lack of Vulkan sparse support as needed for running many newer Windows DirectX 12 games atop Valve's Steam Play with Proton using VKD3D-Proton. Intel recently did implement Vulkan sparse support for ANV in Mesa 23.3 but it only works with their yet-to-be-upstreamed and still-experimental Xe kernel driver. But now Intel Linux graphics driver engineers have managed to pull off a solution for getting the sparse resources supported while using the existing i915 kernel DRM driver...

It was a decade ago that a security researcher commented on X.Org Server security being even "worse than it looks" and that the GLX code for example was "80,000 lines of sheer terror" and hundreds of bugs being uncovered throughout the codebase. In 2023 new X.Org security vulnerabilities continue to be uncovered, two of which were made public today and date back to X11R2 code from the year 1988...

Today the review embargo lifts on the first AMD-powered Framework laptop.

Checking for the presence of Intel virtualization (VMX) support and it being enabled can be easily achieved by looking at the flags in /proc/cpuinfo. But to this point AMD virtualization (SVM) has always been shown to user-space via /proc/cpuinfo even when the BIOS/platform has disabled SVM functionality. Finally for Linux 6.7 this oversight is being corrected...
