Briefings
At the 2026 GNU Tools Cauldron, Kees Cook presented changes to the GCC compiler suite to support forward-edge control-flow integrity (CFI) for the Linux kernel. This initiative aims to prevent exploits by ensuring the flow of control remains within intended paths. The evidence indicates this is a new addition to the GCC suite, though specific implementation details and testing results are not provided in the source.
Key points
