The ptmx_get_ioctl function in the ARM kernel in Apple iOS before 7.1 and Apple TV before 6.1 allows local users to gain privileges or cause a denial of service (out-of-bounds memory access and device crash) via a crafted call.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
