Kernels are soft targets. But getting harder. Even the Linux kernel. Ha ha, just kidding. OK, only 90% joking. Some people care about kernel exploitation these days, partially due the increasing need to pop application sandboxes. Apparently, people even care about Linux kernel exploitation since owning a bunch of Android phones is the new hotness. This presentation will look at the state of Linux kernel exploitation: the latest and greatest techniques, how exploitation has gotten slightly harder over the past few years, and what challenges lie ahead for the offensive-minded in the near future on both vanilla and hardened kernels.
