It’s recommended to avoid using the open-source NVIDIA ‘Nouveau’ graphics driver on the current stable Linux 6.3 series as there is a serious bug present that could cause varying issues to your system.

There is a use-after-free issue within the Nouveau DRM kernel driver and it can cause corruption of kernel memory. Use-after-free issues are also a potential security vulnerability but it’s possible this corrupted kernel memory could lead to file-system corruption or other system issues.
