Throwhammer. Nice.  ;D

We show that even at relatively modest network speeds of 10Gbps, it is possible to flip bits in a victim machine from across the network

Well pfsense can't do 10Gbps so its not vulnerable. /s

These attacks keep getting worse.

It currently requires RDMA where you can control the timing and target memory. Not to mention non-ECC memory and memory that is affected by rowhammer.

I don't use ECC, but my DDR3 in unaffected by rowhammer. Validating both by research and using memtest rowhammer mode

Most high end NICs that are not doing RDMA are going to DMA interrupt coalesce and not let you choose where to write to memory. I am not sure how applicable this attack actually is.
