Description of problem:
I have upgraded my Fedora 25 to Fedora 26 today.

After that, when the system started, this SELinux Alert appeared
SELinux is preventing modprobe from 'module_load' accesses on the system /usr/lib/modules/4.11.9-300.fc26.x86_64/misc/vboxdrv.ko.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that modprobe should be allowed module_load access on the vboxdrv.ko system by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'modprobe' --raw | audit2allow -M my-modprobe
# semodule -X 300 -i my-modprobe.pp
