Hardened malloc one of the most significant GrapheneOS security features but not very talked about. You can install and use it on any Linux distro you want. Certain distros like secureblue come with it too! You can also do the same with Linux-hardened, which was maintained by us. One of our maintainers also handles the Hardened Malloc package for Rocky Linux. To be honest, none of our team members are like that. They're not even paranoid, just talented. If I talked about how I did my computing here then the Linux Defence Force will have on rooftops.
