CVE-2017-13855 is a type confusion vulnerability in the Kernel component of certain Apple products, affecting iOS before 11.2, macOS before 10.13.2, tvOS before 11.2, and watchOS before 4.2. Apple states that a crafted application can trigger the type confusion condition and bypass intended memory-read restrictions, allowing the application to read restricted memory. The issue was addressed through improved memory handling. Apple credited Jann Horn of Google Project Zero.
