Libvirt is vulnerable to NULL pointer dereference. The vulnerability is caused by a race condition due to the simultaneous detachment of a host interface while collecting the list of interfaces using the virConnectListAllInterfaces API. This race condition leads to a situation where the path variable can become NULL while still being accessed, resulting in Denial of Service (DoS).
