That's true, but the implication of "zero day" in a new story is code execution, because those are the only zero days that make the news. You can just read this thread and see that several people commenting here clearly believe these bugs were comparable to code execution. The article, uh, does not go out of its way to clear up the ambiguity.

The first day that anything is available is technically “day 0”, but if I told you I had a PS5 zero day you’d assume I’d discovered a major compromise of the PS5, not that I’d managed to purchase a console the day they went on sale.
