Navigating the Mythos-haunted world of platform security

Red Hat News - Wed, 04/08/2026 - 08:00
The preview release of Claude Mythos presents a massive challenge for IT security experts, as well as an opportunity (at least for the organizations that can afford it). Mythos represents a new category of frontier model that can not only identify complex memory safety issues and logic flaws hidden in legacy code but also exploit them in increasingly sophisticated ways. This dramatically compounds and expands the outsize role currently played by AI-driven vulnerability scanning both in corporate IT security teams and open source communities. Mythos, however, represents more than a deluge of AI

MCP security: Logging and runtime security measures

Red Hat News - Wed, 04/08/2026 - 08:00
Model Context Protocol (MCP) servers often execute code or commands as instructed by an AI agent, exposing them to various risks. To help mitigate these risks, you should implement strict runtime security measures to contain what the server can do and to sanitize what it processes.As discussed in our previous blog post, MCP security: Implementing robust authentication and authorization, an important aspect of MCP security is the ability to monitor autonomous agent behaviour and identify potential threats in real-time. By maintaining a detailed audit trail of tool invocations, authentication ev

For those that like to make remarks about AMD "fine wine" especially when it comes to open-source Linux drivers and/or nostalgic about feature work on really old hardware, to much amusement there are new patches today for the AMD InterWave ISA sound card from the 1990s...

Ubuntu 26.04 Provides More Performance For AMD Ryzen AI Max "Strix Halo"

Phoronix - Tue, 04/07/2026 - 23:15
Last week I provided benchmarks to quantify how the AMD Strix Halo graphics performance has evolved since launch one year ago, in today's article is a look at how the Zen 5 CPU performance with the flagship Ryzen AI Max+ 395 has evolved under Linux in the year since these exciting APUs began making their way to high-end laptops and desktops. Complementing the nice Radeon 8060S performance gains are also some nice CPU performance benefits quantified when using Ubuntu 26.04.
