Kernel

My aim for this post is to provide some insights for getting into Linux kernel vulnerability research and exploit development

Let's kick things off with a modern day staple for local privilege escalation (LPE) in Linux Kernel Exploitation, modprobe_path.

Thought the Linternals series was hype? Get ready for the even SEO friendlier LiKE, a series on Linux kernel exploitation.

I know you've all been waiting for it, that's right, we're going to be taking a dive into another exciting aspect of Linux internals: memory allocators!

In this part of our journey into virtual memory in Linux, we cover the mystical kernel memory map and all it entails.

An introductory look into patching, instrumenting and debugging Linux kernel modules.

We continue our journey to understand virtual memory in Linux, as we take a closer look at the user virtual address space.

Recently I discovered a vulnerability in the Linux kernel that's been lurking there since 4.8 (July 2016)! CVE-2022-0435 is a remotely and locally exploitable stack overflow in the TIPC networking module of the Linux kernel

A post sharing some insights into the process behind responsibly disclosing vulnerabilities in the Linux kernel...

Alright, let's get stuck into some Linternals! As the title suggests, this post will be exploring the ins and outs of virtual memory with regards to modern Linux systems.
