Just like about any OS that tries to optimize at least a bit: meltdown
allows to read all of the main memory.
There is a meltdown gnumach branch to mitigate that part, but my time
has been caught by the need for upstreaming glibc.

It's worth keeping in mind that there are very likely important security bugs far more dangerous than rowhammer-style attacks in Mach, let alone the Hurd. Security-critical applications should be pretty cautious.
