Looks related to the the teefer driver.
Is VirtualBox at the latest version? May want to try with the latest version of SEP, 12.1.6 MP4.
You could also remove the firewall only and see if that fixes it.
Besides that, the bsod dump will need to be sent to Symantec for investigation. But I'd make sure both products are at the latest version as this could've been fixed already.
