The Linux Kernel Bug That Turns a Network Tool Into a Root Exploit

📅 July 23, 2026 📂 Systems & Hardware

A newly discovered Linux kernel exploit (CVE-2026-46331) turns the Traffic Control subsystem—a tool meant to manage network bandwidth—into a local privilege escalation weapon. Any unprivileged user can become root on vulnerable systems. The fix is in v7.1-rc7, but thousands of servers remain unpatched. This is a stark reminder that internal kernel subsystems are the new attack surface.

The Hidden Power of WSL2: How to Replace Its Kernel and What It Costs You

📅 July 7, 2026 📂 Systems & Hardware

Most WSL2 users never touch the kernel—but if you’re a power user hungry for bleeding-edge features, you can swap it with a rolling mainline build. This guide walks through the exact steps, the hidden trade-offs (broken Windows interop), and why the freedom to customize might not be worth the fragility. A must-read for anyone who wants to push WSL2 beyond its ‘just works’ promise.
