kernel: two remote denial of service vulnerabilities

Package(s):kernel CVE #(s):CVE-2015-5364 CVE-2015-5366
Created:July 13, 2015 Updated:June 14, 2016
Description: From the CVE assignment email, which was evidently prompted by a tweet from grsecurity:

It appears that you are primarily asking for a CVE ID for the issue involving the absence of a cond_resched call. Use CVE-2015-5364.

However, the presence of "return -EAGAIN" may also have been a security problem in some realistic circumstances. For example, maybe there's an attacker who can't transmit a flood with invalid checksums, but can sometimes inject one packet with an invalid checksum. The goal of this attacker isn't to cause a system hang; the goal is to cause an EPOLLET epoll application to stop reading for an indefinitely long period of time. This scenario can't also be covered by CVE-2015-5364. Is it better to have no CVE ID at all, e.g., is udp_recvmsg/udpv6_recvmsg simply not intended to defend against this scenario?
