This is not "how to exploit NULL pointers" ... this is "how to exploit a kernel NULL function pointer". Well, duh. In other news, security researches find exploit for systems with blank root password.

I think this is just one facet of a larger problem, which I call the "impeding American Cultural Revolution" aka "The rise of the idiocracy". If you look at conditions today, they are similar to the start of the Chinese Cultural Revolution: disrespect for the science and facts (climate change deniers, creationists, birthers, teabaggers, health care death panelers, etc) and the glorification of the common man (Joe the Plumber, Sarah Palin, Glenn Beck, Michele Bachmann, Gretchen Carlson dumbing herself down, etc). The scenario which scares me is: the idiots vote Sarah Palin into office, and she prevents control of greenhouse gases until a massive global catastrophe (where we lose a significant portion of the world's arable land) that makes the Three Years of Natural Disasters look like a minor problem...
