RFC: As I understand it this exploit requires local access and cannot be deployed remotely. Is this a correct analysis?

right, but remote code execution comes in many different ways. Having a machine vulnerable to this kind of privilege escalation is a really bad thing.

Certainly. I don't discount that any exploit is 'really bad'. I like my OS of choice to be as free of exploits as it can possibly be. However, some of the material I was reading involved areas of Linux that I have little if any knowledge of value with, so I thought I'd as the question.

It's a LOCAL privilege escalation vulnerability. You need sufficient access to be able to execute arbitrary code locally on the machine. You would need a remote code execution vulnerability in an exposed service (VPN, web server, game server and so on) before an attacker could chain to this to get remote root on your system.
