CVE-2018-14646

The Linux kernel was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service.

If you're not running container images, or creating net namepaces exposed to potentially malicious workloads this issue has a security impact of moderate. This issue has an important impact if the system is being used to run container images with untrusted content, such as an OpenShift Container Platform compute node.
