[SOLVED] nvidia: module verification failed: ... tainting kernel

$ sudo dmesg | grep missing
[    4.525359] nvidia: module verification failed: signature and/or required key missing - tainting kernel

Is it normal or dangerous?

Because it's an out of tree module, those are not signed by the key generated during the main kernel build.
