Insider trading usually implies coming into possession of confidential information and acting on it. Trading on non-public information that results from your own research and then announcing it is not illegal.
Imagine someone buying stock and then saying the company is good. Not very controversial is it. Warren Buffet does it. Shorting stock and saying the company is bad is just the flip side of it.
In fact, there are equity research companies that do specifically that (e.g. Muddy Waters). Whether that research holds water or not is for the market to determine (AMD is up on the day).

Correct. I'm not referring to this. I'm referring to trading on information discerned from communications with e.g. AMD but prior to disclosure of the vulnerability, especially if those communications which establish e.g. timelines are only disclosed after trading
Hence my point about trading upon understanding AMD's response timeline e.g. from emailing them.
Generally speaking, a company communicating information to you does not bar you from trading unless you explicitly agree to refrain from making trades.
