Turns out the problem is already fixed in current kernels. min_len in
nfnetlink_check_attributes was calculated incorrectly, which resulted in attrlen
beeing larger than the attribute really was. When the entire packet was parsed
we still had attrlen > 0, and if the memory contents behind the packet data by
accident looked like a valid attribute, it was also parsed, but usually didn't
contain valid attribute numbers, so the packet was dropped.
