FreeBSD-SA-24:18.ctl impacted systems

Good day, folks.

I am seeking clarification of statements in https://www.freebsd.org/security/advisories/FreeBSD-SA-24:18.ctl.asc.
Section III, Impact says “A malicious guest could cause a Denial of Service (DoS) on the host.”
Does this imply that only FreeBSD systems acting as a Virtualization Manager are impacted?  Or could other VM hosts be impacted by a FreeBSD guest?  And are bare metal installations affected at all?
Also, I am unfamiliar with ctld(8) – is it only used with virtualization, or could it be used in the aforementioned bare metal FreeBSD, and for what purpose?

Thank you.
Steve Wall
