CVE ID :CVE-2026-61477
Published : Aug. 7, 2026, 2:17 p.m. | 1 hour, 10 minutes ago
Description :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.
Severity: 2.3 | LOW
