libvirt.so is vulnerable to Off-by-one Error. The vulnerability is due to a miscalculation in the udevListInterfacesByStatus function when the number of interfaces exceeds the size of the names array. This issue can be exploited by sending specially crafted data to the libvirt daemon, enabling an unprivileged attacker to conduct a denial of service by crashing the daemon.
