Fuzzing the OpenBSD Kernel [pdf] (openbsd.org)

This seems to be slides from a recent OpenBSD meetup where they were discussing the implementation of syzkaller[1], an open source tool from Google written in Go, to fuzz C kernels.

Then it lists 9 issues found in the OpenBSD kernel, including two[2][3] issues with kqueue.

Pretty cool stuff!

How long was syzkaller ran and on what kind of hardware to find the 9 bugs?

Is there any video of this meeting? That would be great.

I was at the meetup here in Stockholm this past Wednesday where Anton presented these slides and there was no video made. I'm not sure if he's presented the same slides elsewhere though so you might still have some luck.

It was a nice talk by the way.
