What is CVE-2014-7284?
CVE-2014-7284 is a medium-severity vulnerability in Linux kernel, published on 13 Oct 2014. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-200
