I've worked to mitigate other vulnerabilities within Google. at least with the vulnerability I helped on, I'm surprised at how good the information containment was. Based on my area of work and job title, I was notified of the software that was vulnerable and to contact them with further info if we used it. I wasn't allowed to talk to others without explicit consent, so I talked to my central contact to find the right PoC in my neighbor teams to know who I was allowed to pull into a room for any joint strategies. To everyone else, I simply said "sorry. On call is busy this week. I'm working on mitigating an undisclosed vulnerability." No questions asked. To this day I'm still not 100% sure the vulnerability is public so none of my peers know anything more than the time window in which I was distracted.
