The Autofill implementation in Google Chrome before 51.0.2704.63 mishandles the interaction between field updates and JavaScript code that triggers a frame deletion, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted web site, a different vulnerability than CVE-2016-1701.
