Vulnerability CVE-2019-12615


Published: 2019-06-03

Description:
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).

Type:

CWE-476

(NULL Pointer Dereference)

Vendor: Linux
Product: Linux kernel 
Version: 5.1.6;
