Yeah, the white papers are pretty clear on how to replicate it, though it seemed it would still take no small effort to get it working at a higher level (IIRC they used kernel modules to pull it off). Here's the meltdown repo from the paper if your interested: https://github.com/IAIK/meltdown

In Meltdown Update Kernel doesnt boot

philsnow·Jan 9, 2018

you're being downvoted but the first non-trivial program `./kaslr` fetches the physical map offset of the running kernel: https://github.com/IAIK/meltdown/#demo-2-breaking-kaslr-kasl... Note they do say > This demo uses Meltdown to leak the (secret) randomization of the direct physical map. This demo requires root privileges to speed up the process. The paper describes a variant which does not require root privileges. but I don't know how much allowing it to sudo speeds up the process.
