CVE-2018-14678 CrOS: Vulnerability reported in Linux kernel

Project Member Reported by vomit.go...@appspot.gserviceaccount.com, Oct 2 
VOMIT (go/vomit) has received an external vulnerability report for the Linux kernel. 

Advisory: CVE-2018-14678
  Details: http://vomit.googleplex.com/advisory?id=CVE/CVE-2018-14678
  CVSS severity score: 7.2/10.0
  Description:

An issue was discovered in the Linux kernel through 4.17.11, as used in Xen through 4.11.x. The xen_failsafe_callback entry point in arch/x86/entry/entry_64.S does not properly maintain RBX, which allows local users to cause a denial of service (uninitialized memory usage and system crash). Within Xen, 64-bit x86 PV Linux guest OS users can trigger a guest OS crash or possibly gain privileges.
