However, recently my kernel was automatically upgraded to 4.16 and it broke the nvidia driver. Running 'dkms autoinstall --all' does not help, it complains about not finding kernel headers (which are installed) and quits. Any ideas on how I can rebuild the kernel module for the new kernel version? Thanks FranciscoThis requires a workaround, a kernel parameter at boot. GRUB_CMDLINE_LINUX_DEFAULT="slab_common.usercopy_fallback=y" Edit the config file like this, $sudo gedit /etc/default/grub Then run $sudo update-grub.
Actually, as of version 390.67-2, that's no longer needed. Quoting : nvidia-graphics-drivers (390.67-2) unstable; urgency=high * Add kmem_cache_create_usercopy.patch from Red Hat, fixing "Bad or missing usercopy whitelist? Kernel memory exposure attempt detected from SLUB object 'nvidia_stack_cache'" on Linux kernels that have disabled CONFIG_HARDENED_USERCOPY_FALLBACK (i.e. linux-image-4.16.0-2-* or newer).
