This repository provides artifacts for Segmentation Fault-Oriented Programming (SFOP), a novel exploitation technique that abuses signal handlers to bypass Intel CET. It includes PoC exploits and demonstrations against Nginx and Ladybird.
The author investigates why segmentation faults are not displayed when using entr to run a C program, discovering that bash's exec optimization suppresses the error message unless the command is run in a subshell or script.
