I can confirm the update introduced a regression on Hirsute (and Impish
I presume). Focal and Groovy work properly. Unfortunately, it's not
related to the security patch, but it stems from the package being
rebuilt with the newer toolchain in Hirsute, so removing the patch won't
fix the issue.
I am currently investigating how to fix this.

Bug description:
Ubuntu 21.04 on Raspberry Pi. isc-dhcp-server was working just fine
with version V4.4.1-2.2-ubuntu6.
I got updated to V4.4.1-2.2ubuntu6.1 and now isc-dhcp-server refuses
to start with the error "Can't clone pool group".
I backed off to the prior version and it's working as before, so
something in the V4.4.1-2.2ubuntu6.1 update has broken config file
parsing.
Here's the subnet section of the failing config. Removing the "pool"
declaration from the subnet declaration eliminates the error, but of
course, that's not a working configuration.
subnet 192.168.92.0 netmask 255.255.255.0 {
option domain-search "foo.com", "dyn.foo.com";
option broadcast-address 192.168.92.255;
allow duplicates;
ddns-updates off;
pool {
ddns-updates on;
allow unknown-clients;
option domain-name "dyn.foo.com";
ddns-rev-domainname "dhcp";
default-lease-time 86400;
max-lease-time 86400;
range 192.168.92.101 192.168.92.127;
}
}
This was also noted at least twice in the Ubuntu forums:
