Hi David,
Having just watched your LPC presentation; there was a question for more
things to check, but also running out ot time.
One thing that did occur to me; is that when you have the user-kernel
bounary, then it should be possible to find the case where a user
originating variable (result of copy-from-user, syscall argument, etc..)
is used as an array index (without proper guarding like
array_index_nospec()).
~hth,
Peter
