Staging: comedi: integer overflow in do_insnlist_ioctl()
There is an integer overflow here that could cause memory corruption
on 32 bit systems.
insnlist.n_insns could be a very high value size calculation for
kmalloc() could overflow resulting in a smaller "insns" than
expected. In the for (i = 0; i < insnlist.n_insns; i++) {... loop
we would read past the end of the buffer, possibly corrupting memory
as well.
