Yuval Hanoch Hirschenbein discusses discovering a 40-year-old kernel bug in UNIX domain sockets on the DEFCON 34 main stage. The bug manifests as a consistent crash when his VM running an SSH server inside an iOS app starts up on a freshly booted device, pointing to a deterministic issue rather than ASLR or race conditions.
Background
DEFCON 34 took place in July 2026 in Las Vegas. UNIX domain sockets are a 40-year-old IPC mechanism in Unix-like systems, still relevant on iOS.
