Comment 2 Martin Osvald 🛹 2023-06-23 07:29:14 UTC
Dhcp is not affected:

https://bugzilla.redhat.com/show_bug.cgi?id=2216581#c3
~~~
According to upstream article [1] this is only affecting supported preview version. We do not have it in RHEL or even in Fedora. 
That is also why upstream release notes [2] of latest 9.16 does not mention this vulnerability.
We are not affected by this one. In any release or component. Nor have a change to backport.

Can all those bugs be closed?
