It is unlikely something to be broken in the networking stack. Better question to ask is who is 192.168.100.100 and why it started telling about itself to be 192.168.100.255... Hm?
I may have overlooked something but from the source it looks like this might just mean that a packet from 192.168.100.100 to 192.168.100.255 has been received on an interface RP filter considers wrong.
Output of "ip addr show", "ip route show" and "ip neigh show" would definitely tell us more.
