CVE-2018-14646 CrOS: Vulnerability reported in Linux kernel

Project Member Reported by vomit.go...@appspot.gserviceaccount.com, Dec 20 
VOMIT (go/vomit) has received an external vulnerability report for the Linux kernel. 

Advisory: CVE-2018-14646
  Details: http://vomit.googleplex.com/advisory?id=CVE/CVE-2018-14646
  CVSS severity score: 4.9/10.0
  Description:

The Linux kernel before 4.15-rc8 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.

The upstream fix is
   f428fe4a04cc ("rtnetlink: give a user socket to get_target_net()")

This patch is present in chromeos-4.19. Older kernels do not have this commit.
Kenrels <= 4.14 do not have the affected functionality introduced with get_target_net(). Marking as WontFix.
