CVE-2017-15274 CrOS: Vulnerability reported in Linux kernel

Project Member Reported by vomit.go...@appspot.gserviceaccount.com, Nov 4 2017

Issue description

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

Advisory: CVE-2017-15274
  Details: http://vomit.googleplex.com/advisory?id=CVE/CVE-2017-15274
  CVSS severity score: 4.9/10.0
  Description:

security/keys/keyctl.c in the Linux kernel before 4.11.5 does not consider the case of a NULL payload in conjunction with a nonzero length value, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192.

5649645d725c73df4 KEYS: fix dereferencing NULL payload with nonzero length

Labels: Pri-2
Labels: -Pri-2 Pri-1
Status: WontFix (was: Assigned)
Already fixed in chromeos-4.4 starting with M-62 through merge of v4.4.70. Won't fix in older kernels; there are too many problems in the affected file, and fixing just one or two does not add much if any value.
Marking as WontFix.
