CUDA is not as 1 to 1 locked as the opengl and vulkan the following is a good read..
Particular the next section
Then notice particular Nvidia kernel modules only support 1 version of CUDA. Also you update your kernel module you cannot use CUDA older than it.
So you upgrade your nvidia kernel module those old CUDA programs that depend on some old CUDA quirk that no longer there no longer work.
People like avis are not very truthful about this. Yes CUDA is just a userspace library that happens to be fairly picky what kernel module it works with.
