The current text at https://www.deepspeed.ai/tutorials/advanced-install/#cuda-version-mismatch was confusing to me:

You have a misaligned version of CUDA installed compared to the version of CUDA used to compile torch. We only require that major version match (e.g., 11.1 and 11.8 are OK). However a mismatch in the major version may result in unexpected behavior and errors.

The word "however" made me wonder if there was a typo, and the sentence was supposed to say that even minor version differences could result in unexpected behavior.

But based on the messages in assert_no_cuda_mismatch, my guess is that minor version differences are fine, and the sentence was just a bit unclear.
