Using vanilla fedora kernel. Is that a bug or i need to do something to fix that?

After some research i found that “Kernel Verification” means that linux kernel is “tainted”

You can check what couse this in logs by typing command journalctl -k | grep taint

In my case kernel is mark “tainted” due to Nvidia Proprietary driver

journalctl -k | grep taint - output:

kernel: nvidia: loading out-of-tree module taints kernel.
kernel: nvidia: module license 'NVIDIA' taints kernel.
kernel: Disabling lock debugging due to kernel taint
kernel: nvidia: module verification failed: signature and/or required key missing - tainting kernel
kernel: nvidia_uvm: module uses symbols nvUvmInterfaceDisableAccessCntr from proprietary module nvidia, inheriting taint.
