The kernel in Apple iOS before 9.3.3, OS X before 10.11.6, tvOS before 9.2.2, and watchOS before 2.2.2 allows local users to gain privileges or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2016-1863 and CVE-2016-4653.

The specific version of Mac OS X that the system is running is reportedly affected by the following vulnerabilities:
