An issue was discovered in certain Apple products. iOS before 11.4 is affected. macOS before 10.13.5 is affected. tvOS before 11.4 is affected. watchOS before 4.3.1 is affected. The issue involves the "Kernel" component. A buffer overflow in mptcp_usr_connectx allows attackers to execute arbitrary code in a privileged context via a crafted app.

CVE-2016-7644 A survey of recent iOS kernel exploits - Project Zero
Posted by Brandon Azad, Project Zero
I recently found myself wishing for a single online reference providing a brief summary of the high-level exploit flow of every public iOS kernel exploit in recent years; since no such document existed, I decided to create it here.
This post summarizes original iOS kernel exploits from local app context targeting iOS 10 through iOS 13, focusing on the high-level exploit flow from the initial primitive granted by the vulnerability to kernel read/write. At the end of this post, we will briefly look at iOS kernel exploit mitigations (in both hardware and software) and how they map onto the techniques used in the exploits.
This isn't your typical P0 blog post: There is no gripping zero-day exploitation, or novel exploitation research, or thrilling mal
