Description Dhananjay Arunesh 2019-06-07 08:14:38 UTC
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).
