CVE-2016-1726
WebKit, as used in Apple iOS before 9.2.1 and Safari before 9.0.3, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, a different vulnerability than CVE-2016-1723 and CVE-2016-1725.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
