Synology does have some vulnerable models and does not appear to have
released any fixes yet.

However, I don't think this is a big concern for appliances like that.
Effective exploitation of meltdown or spectre requires running code on the

I was planning on getting a Synology
NAS....should I be concerned about security? I assumed that they would have
this problem locked down on their new hardware...but I am not sure.
