More details can be found on (https://github.com/nonamecoder/CVE-2022-27254) and his DEFCON talk (https://www.youtube.com/watch?v=AxkRnUnvYWw)
Turns out this may not be the Honda-only issue. A few days ago we found another fixed codes vuln, but it's on Nissan Sylphy Classic 2021 this time.
As we can see from the packets diagram, no signs of rolling codes applied to lock or unlock commands.
