CrOS: CVE-2017-9984: Vulnerability reported in Linux kernel

Project Member Reported by vomit.go...@appspot.gserviceaccount.com, Jul 1 2017

Issue description

VOMIT (go/vomit) has received an external vulnerability report for the Linux kernel. 

Advisory: CVE-2017-9984
  Details: http://vomit.googleplex.com/advisory?id=CVE/CVE-2017-9984
  CVSS severity score: 7.2/10.0
  Description:

The snd_msnd_interrupt function in sound/isa/msnd/msnd_pinnacle.c in the Linux kernel through 4.11.7 allows local users to cause a denial of service (over-boundary access) or possibly have unspecified other impact by changing the value of a message queue head pointer between two kernel reads of that value, aka a "double fetch" vulnerability.

Only affects sound devices connected through ISA bus, which we don't have.
Upstream does not currently have a fix. If a fix will be provided, we'll get it through a stable merge in 4.4. Won't fix in older kernels.
