Linux's KVM With CET Virtualization Is Causing Some Hosts To Hang

Introduced to the Linux kernel last year was Control-flow Enforcement Technology "CET" virtualization for modern AMD and Intel CPUs . This complements CET that has existed in Linux for quite some time but it's new now to the KVM virtualization world, but some yet to be diagnosed problems are causing some hosts to hang when making use of this virtualization security feature.

CET is a hardware-based security feature to prevent against common ROP and COP/JOP attacks. While Control-flow Enforcement Technology has been working out well

Older AMD GPUs Score Another Open-Source Driver Win From Valve: DRM Format Modifiers

Timur Kristóf of Valve's Linux open-source graphics driver team isn't done driving new improvements to aging AMD GCN 1.0/1.1 era graphics cards on Linux. Beyond enhancing display support for older APUs , transitioning GCN 1.0/1 GPUs from the legacy Radeon driver to modern AMDGPU driver , and a host of other fixes and optimizations for these old GPUs going back to the Radeon HD 7000 series, he has another notable addition that was announced today. These

Arm Mali G1 Pro Now Working With Open-Source PanVK & Panfrost Drivers

The PanVK Vulkan driver and Panfrost Gallium3D driver for Arm Mali graphics hardware is now supporting the latest "v14" hardware GPU hardware with the Arm Mali G1-Pro now being advertised as supported.

The top-end Mali hardware support by Panfrost and PanVK until now was the Mali-G725 that was introduced in 2024. Now with Mesa 26.2 due for release next quarter, the Mali G1-Pro is advertised as supported but not yet advertising the

Linux Driver Posted For Intel Silicon Security Engine Interface "ISSEI"

Since Intel Meteor Lake has been the Intel Silicon Security Engine to serve as a silicon root-of-trust for secure firmware loading, boot measurements, and similar functionality. This Intel Silicon Security Engine has been built on with Lunar Lake and Panther Lake as well as set to take on more importance with future Intel hardware platforms. We are now seeing a Linux driver come for this silicon RoT with the Intel Silicon Security Engine Interface (ISSEI).

Intel software engineer Alexander Usyskin posted today the patch series providing the initial Linux

Fragnesia Made Public As Latest Linux Local Privilege Escalation Vulnerability

Following last week's disclosure of the Dirty Frag vulnerability for the Linux kernel , which only finished being patched up in mainline on Monday , Fragnesia is now public as a similar local privilege escalation (LPE) vulnerability.

Announced today on the open-source security mailing list by V12 Security is Fragnesia as a local privilege escalation exploit that is of the same vulnerability class as Dirty Frag. Fragnesia centers around a separate bug within the ESP/XFRM code with a logic bug to allow arbitrary byte writes into the kernel

GCC 16 Produces Faster Binaries Than GCC 15, Competitive Race With LLVM Clang 22

GCC 16.1 released at the end of April as the latest major, annual feature release to the GNU Compiler Collection. Early benchmarks showed some nice leads for GCC 16 over GCC 15 . Continued testing of the new GCC 16 compiler has continued to show overall better performance of the resulting binaries than using GCC 15 on the same hardware and same compiler flags. That led many to wonder about the GCC 16 performance up against the latest LLVM/Clang open-source compiler, which is the
