RSS feed is not online for some time. I was looking for something similar what you are asking. But there is no 1 real page that shows it all.
There are some pages to specifics:
OpenSSH: https://support.checkpoint.com/results/sk/sk65269
OpenSSL: https://support.checkpoint.com/results/sk/sk92447
NTP: https://support.checkpoint.com/results/sk/sk110271
And so on. BUT I have to say, Check Point is well known for the low amount of critical vulnerabilities on the products. If you compare them with other vendors.
