The (1) pipe_read and (2) pipe_write implementations in fs/pipe.c in
the Linux kernel before 3.16 do not properly consider the side effects
of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls,
which allows local users to cause a denial of service (system crash)
or possibly gain privileges via a crafted application, aka an "I/O
vector array overrun."
