I guess what you call CUDA version is this:

nvidia-cuda-dev | 11.8.89~11.8.0-5~deb12u1 | stable/non-free           | amd64, arm64, ppc64el
nvidia-cuda-dev | 12.2.140~12.2.2-2        | testing/non-free          | amd64, arm64, ppc64el
nvidia-cuda-dev | 12.3.101~12.3.2-1        | unstable/non-free         | amd64, arm64, ppc64el
nvidia-cuda-dev | 12.4.99~12.4.0-2         | experimental/non-free     | amd64, arm64, ppc64el

so I'm going to file a serious bug on nvidia-cuda-dev so that it
does not propagate to testing, not even accidentally.

(If you have a better idea, please say so)

Thanks.
