Exploitation Summary
EIP tracks 2 public exploits for CVE-2016-4669. PoCs published by Google Security Research, i-o-s.
AI-analyzed exploit summary This exploit targets a vulnerability in the XNU kernel's MIG (Mach Interface Generator) code, specifically in the `mach_ports_register` function. The issue arises from a mismatch between the `init_port_set.count` and `init_port_setCnt` values, leading to out-of-bounds memory access and potential use-after-free (UaF) conditions.
Description
An issue was discovered in certain Apple products. iOS before 10.1 is affected. macOS before 10.12.1 is affected. tvOS before 10.0.1 is affected. watchOS before 3.1 is affected. The issue involves the "Kernel" component. It allows local users to execute arbitrary code in a privileged context or cause a denial of service (MIG code mishandling and system crash) via unspecified vectors.
