Comment 1 Reto Gantenbein 2026-04-13 21:52:22 UTC 
I believe this is a false positive as the CVE is reported against dnsmasq and dnsmasq is not shipped as part of the Incus package in Fedora. Although incus depends on dnsmasq the referenced vulnerability happened to be in a much older version of dnsmasq as currently shipped with Fedora.
