Ubuntu Linux was welcomed to Pwn2Own by the Chaitin Security Research Lab. They leveraged a Linux kernel heap out-of-bounds access bug to earn themselves $15,000 and 3 Master of Pwn points. We’ve seen folks pop calc before, but popping xcalc was a nice touch.

No details given by Chaitin Security or the article but Ubuntu patched two kernel bugs the same day the exploit was made public.
