One thing I worry about, probably unnecessarily, is anything with a sense of urgency.

HEY GUYS WE JUST FOUND A GOLANG COMPILER BUG AND FATAL PANICS!

Everyone is like “Hmm. I need to fix this now.”

So, 99% probability it’s what it is. 1% it’s some secret defensive thing because there was a bad stupid zero day someone would get fired over or that could leave the world in shambles if uncovered, or maybe something else needed to be swept under the rug, or maybe someone wants to distract while they introduce a new vulnerability.

I don’t think this with CVEs, but when someone’s like “install this patch everybody!” the dim red light flickers on.
