This was an interesting finding that John led. He stumbled upon it after poking around files on his computer in keybase, quickly getting the team to do further research on it. John was on windows when he noticed the potential issue, Kanshi and Kirtaner loaded up MACOS to test another OS, with Kirtaner getting deeper into a second round of findings. I doubled up on Windows with John.
John has written a great blog on the findings at https://johnjhacking.com/blog/cve-2021-23827/
