To sign kernel modules to make work with secure boot, this 2 posts are a good reference , I haven't test my self:
or google for "virtualbox fedora secure boot" ,
1- if you don't need usb or just for testing , go to setting usb and disable usb , for that you have to have vm machine off .
2 - with firefox click here : http://download.virtualbox.org/virtualbox/5.0.14/Oracle_VM_VirtualBox_Extension_Pack-5.0.14.vbox-extpack firefox should ask if you want install with vbox something , say yes
3 - after try file -> check for updates , also should install the correct extpackage
if this doesn't do nothing because you install a superior version
rm -rf /usr/lib64/virtualbox/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack as root , and repeat items 2 and 3
anyway , you should use file -> check for updates to update extension pack
