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-2016-4582 and CVE-2016-4653.
Weakness
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
