Not just limited to this concept, some essential kernel security enhancements mentioned in the [blog post][5] include:
* _Support for [core scheduling][6], which allows processes to control which threads will be scheduled across SMT siblings and so can allow them to protect sensitive information from leaking to other untrusted processes on the system._
* _Kernel stack randomisation provides a hardening measure to frustrate attackers wishing to perform memory corruption attacks within the kernel._
* _The BPF subsystem has also seen a number of security enhancements including restricting its use to only privileged processes by default, as well as including the initial efforts to support signed BPF programs as well_
* *The inclusion of the new Landlock Linux Security Module provides another mechanism for application sandboxing to go along with the more traditional methods via either AppArmor or SELinux. *
