Hey there, kernel enthusiasts! Welcome back to another episode of Linux Kernel. I'm your host, and wow, do I have some interesting stuff to share with you today from March 11th, 2026.
You know what I love about kernel development? It's not always about flashy new features or groundbreaking performance improvements. Sometimes the most important work happens in the shadows - the kind of careful, methodical bug fixing that keeps our systems secure and stable. And today is absolutely one of those days.
We've got two commits from Linus himself, and both are perfect examples of why maintenance work is so crucial in kernel development. Let's start with something that caught my attention - some serious security fixes in the SMB server code.
The first commit pulls in fixes for ksmbd, which is the kernel's SMB server implementation. Now, if you're not familiar with SMB, it's the protocol that lets you share files between computers - you've probably used it without even knowing it. Steve French and the team identified some pretty nasty use-after-free…
What's a use-after-free? Think of it like this - imagine you're at a coffee shop, you finish your drink, throw away the cup, but then someone…
