The [hardened memory allocator (hardened_malloc)](https://github.com/GrapheneOS/hardened_malloc) from GrapheneOS can be used on general Linux distributions, though [only for some programs](https://www.kicksecure.com/wiki/Hardened_Malloc).
Kicksecure installs it by default (though not enabled by default) and provides [in&#8209;depth usage instructions](https://www.kicksecure.com/wiki/Hardened_Malloc) relevant to all distributions. On Arch-based systems, hardened_malloc is [available through the AUR](https://wiki.archlinux.org/title/Security#Hardened_malloc). Divested Computing Group maintains a [Fedora build](https://github.com/divestedcg/rpm-hardened_malloc).

On Arch-based systems, hardened_malloc is [available through the AUR](https://wiki.archlinux.org/title/Security#Hardened_malloc). Divested Computing Group maintains an x86_64 [Fedora build](https://github.com/divestedcg/rpm-hardened_malloc) with micro-architecture optimized builds (x86_64_v3, x86_64_v4, etc). SecureBlue provides a [copr repository](https://copr.fedorainfracloud.org/coprs/secureblue/hardened_malloc/) for Fedora with both x86_64 and aarch64 builds, albeit without micro-architecture optimized builds like Divested Computing Group.
