PHP Critical Update

Hello,
Does anybody know how to properly upgrade for the new php?

I have tried the following:
sudo apt update && apt upgrade
sudo apt-get update
sudo apt-get upgrade
sudo apt-get --fix-missing upgrade
sudo apt-get full-upgrade

And php is still running at 8.3.6.

Thank you.

I think 8.3.6 is fine. Anything less would be bad.
