Merged as part of Linux 5.18 is Intel's Indirect Branch Tracking (IBT) support as part of CET (Control Flow Enforcement) technology. Indirect Branch Tracking is intended to help protect against JUMP/CALL oriented attacks as part of CET's control-flow integrity protections. Meanwhile still being worked on is "FineIBT" as a more compiler-hardened version built atop Intel CET/IBT...
