You can find some of  the references in Barnaby's previous
presentation, archived at on the CanSecWest site.

Vector would imply simple, single, instance, which would
be inappropriate... as Barnaby's class embodies many
individual attack vectors across many pieces of ARM/PXA 
code. "Class" is the appropriate term to use.

And though people may have known about exploiting
null derefs through the interrupt vector table, credit goes
to Barnaby for documenting and explaining the methodology
publicly - which if anyone else knew about it, they didn't do.
