> they also seem to think that a local DoS is not enough for a CVE

Some vendors do not consider local DoS as security issues. I tried to discuss these kind of issues in oss-security but even MITRE refused to assign a CVE.

If the system are not restricted by having quota on every computer resource its trivial for any local user to DoS the system. For the issue to be exploitable, you need to have restrictions in place and to my knowledge the only way to do so in the past was with seLinux. Today of course there is cgroup.
Which one was this specifically? Not all local DoS's are security vulnerabilities, in general there needs to be a trust boundary that is violated, e.g. the ping of death, clearly a single remote ICMP packet shouldn't cause the system to reboot. But what about DoS's that can only be triggered by root? And the whole grey area in between these two extremes?
It was a trivial DoS using a SVG file in a browser. After a a minute, it consumes most of the memory available.
