Doc Text:
When registering a system with Satellite 6 a hostname must be specified. if an additional system is registered with the same hostname, the original system will stop receiving updates from Satellite 6. An attacker with administrative privileges to add systems to a Satellite 6 server could exploit this to prevent other hosts from getting security updates.
