Created dnsmasq tracking bugs for this issue:

Affects: fedora-all [bug 2290850]
Comment 2 Petr Menšík 2024-06-12 16:12:46 UTC 
This issue should be fixed by upstream commit:
https://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=commit;h=65c2d6afd67a032f45f40d7e4d620f5d73e5f07d

Which is not used by our code, because we use HAVE_DNSSEC usually and HAVE_CRYPTOHASH in rhel7. Therefore we do not use built-in sha256 implementation, which needed the fix.
