In the Linux kernel, the following vulnerability has been resolved:
net: fix uninit-value in caif_seqpkt_sendmsg
When nr_segs equal to zero in iovec_from_user, the object
msg->msg_iter.iov is uninit stack memory in caif_seqpkt_sendmsg
which is defined in ___sys_sendmsg. So we cann't just judge
msg->msg_iter.iov->base directlly. We can use nr_segs to judge
msg in caif_seqpkt_sendmsg whether has data buffers.
