Descriptions

A flaw was found in libvirt in the virConnectListAllNodeDevices API in versions before 7.0.0. It only affects hosts with a PCI device and driver that supports mediated devices (e.g., GRID driver). This flaw could be used by an unprivileged client with a read-only connection to crash the libvirt daemon by executing the 'nodedev-list' virsh command. The highest threat from this vulnerability is to system availability.

Se encontró un fallo en libvirt en la API virConnectListAllNodeDevices en versiones anteriores a 7.0.0. Solo afecta a los hosts con un dispositivo PCI y un controlador que admita dispositivos mediados (por ejemplo, el controlador GRID). Este fallo podría ser usado por un cliente no privilegiado con una conexión de solo lectura para bloquear el demonio libvirt al ejecutar el comando virsh "nodedev-list". La mayor amenaza de esta vulnerabilidad es la disponibilidad del sistema
