The kernel in Apple iOS before 6.1 and Apple TV before 5.2 does not properly validate copyin and copyout arguments, which allows local users to bypass intended pointer restrictions and access locations in the first kernel-memory page by specifying a length of less than one page.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
