The net_get_random_once implementation in net/core/utils.c in the Linux
kernel 3.13.x and 3.14.x before 3.14.5 on certain Intel processors does not
perform the intended slow-path operation to initialize random seeds, which
makes it easier for remote attackers to spoof or disrupt IP communication
by leveraging the predictability of TCP sequence numbers, TCP and UDP port
numbers, and IP ID values.
