• kernel-firmware-nvidia-gspx-G06-cuda is at the only available version
560.35.03.
• nvidia-open-driver-G06-signed-cuda-kmp-default has versions
560.35.03_k6.11.8_1-2.1 and 565.57.01_k6.12.6_1-3.1, but only the former can be
installed because of kernel-firmware-nvidia-gspx-G06-cuda's version.
• Notice how the kernel module's versions are kernel-specific, but nothing
prevents zypper from upgrading the kernel to 6.12.6 anyway, leaving users
without a working GPU driver.

The workaround is to keep booting with the old kernel while it's still
available in the system.

It's unclear what blocks timely updates for
kernel-firmware-nvidia-gspx-G06-cuda, since kernel-firmware-nvidia-gspx-G06
(the non-CUDA counterpart) is at the correct version 565.57.01, and both are
shipped by openSUSE.

This is not a one-time issue, it happens regularly, effectively limiting system
updates for NVIDIA CUDA users to the short time windows when
kernel-firmware-nvidia-gspx-G06-cuda's and
nvidia-open-driver-G06-signed-cuda-kmp-default's versions align.
