CVE-2019-12817

HIGH7.5

An issue was discovered in get_vdev_port_node_info in arch/sparc/kernel/mdesc.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup_const of node_info->vdev_port.name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash).
