Staging: comedi: fix integer overflow in do_insnlist_ioctl()
There is a potential integer overflow in do_insnlist_ioctl() if
userspace passes in a large insnlist.n_insns. The call to kmalloc()
would allocate a small buffer, leading to a memory corruption.
The bug was reported by Dan Carpenter <[email protected]>
and Haogang Chen <[email protected]>. The patch was suggested by
Ian Abbott <[email protected]> and Lars-Peter Clausen <[email protected]>.
