CVE detail
CVE-2026-61477
An injection vulnerability was found in libvirt's virtual network driver. The network XML parser does not strip newline characters from DNS TXT record value attributes and SRV record domain/target attributes. These values are written verbatim into the dnsmasq configuration file generated by the network driver, allowing a user with permission to define virtual networks to inject arbitrary dnsmasq configuration directives such as dhcp-script, leading to arbitrary command execution as root.
