Descriptions

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-2016-4582.

El kernel en Apple iOS en versiones anteriores a 9.3.3, OS X en versiones anteriores a 10.11.6, tvOS en versiones anteriores a 9.2.2 y watchOS en versiones anteriores a 2.2.2 permite a usuarios locales obtener privilegios o provocar una denegación de servicio (corrupción de memoria) a través de vectores no especificados, una vulnerabilidad diferente a CVE-2016-1863 y CVE-2016-4582.

This vulnerability allows local attackers to execute arbitrary code on vulnerable installations of Apple OS X. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within IOPMrootDomain. By publishing to this service, an attacker can cause memory corruption. An attacker could leverage this vulnerability to execute arbitrary code with kernel privileges.
