Sam Page works as a Senior Vulnerability Researcher. During his research career he has focused on Linux kernel vulnerability research and exploit development, but has a passion for OS internals and low-level tinkering in general
From its humble beginnings in 1991, the Linux kernel has made its way into everyday life: desktops, servers, smartphones and embedded devices all make use of it. With over 32.8 million Linux users, in addition to 1.6 billion Android users, security is key.
Across the industry we are seeing the security landscape evolve rapidly due to a wide range of factors and the Linux kernel is no exception to this, with vulnerabilities becoming increasingly complex and harder to find.
In this talk Sam explores the challenges surrounding finding impactful vulnerabilities in the Linux kernel today, what kind of vulnerabilities are still out there and the techniques and approaches we can use to find them.
