I have no information here, but it's certainly possible that both sides are not willing to publicly disclose the full extent of the vulnerability. I think that's less wise than usual given what Red Hat is writing and how disputed it is, but that's probably their standard practice.
Some of the comments from Red Hat previously implied that they thought the vulnerability could only be exploited via ptrace, which SELinux denied by default for Docker containers. That's definitely not true; ptrace was used in the PoC because it's easy and likely to win the race condition, but you can also grab file descriptors out of /proc/$pid/fd.
However, the blog post appears to show SELinux stopping attacks that don't involve ptrace, because SELinux forbids writing to an open file or an open network socket that has the wrong context. If Docker believes there are attack vectors that aren't covered by the default SELinux policies (such as writing to something that's not a regular file or network socket), they might be unwilling to disclose that too loudly until Red Hat gets around to saying "Uh, actually please patch".
Your usage is actually correct. Which is great, considering many native English speakers get this one wrong. The heuristic we hear in school is something like "use 'affect' as a verb and 'effect' as a noun," which like many grammar heuristics is of course an oversimplification of reality. Usage of effect as a verb isn't super common in general conversation by native English speakers whereas I think most might choose to say something like "establish authority" instead in this case, but still your intention is still clear.
Because the other comment didn't spell it out: effect is correct there. Effect as a verb means something like "to cause to happen". Don't pretend effect/affect is just a noun/verb split. Both words have meanings as both verbs and nouns. It's best to just learn both meanings of each instead of following some rule that's wrong a fair amount of time.
