Broadband modems using Intel’s bungled Puma 6 chipset can be overloaded and virtually knocked offline by a trivial trickle of packets, it is claimed.Effectively, if there’s someone you don’t like, and they are one of thousands upon thousands of people using a Puma 6-powered home gateway, and you know their public IP address, you can kick them off the internet, we’re told.This week, inquisitive netizens discovered that, when presented with even modest amounts of network traffic as little as a few thousand packets per second spread across various TCP or UDP ports modems equipped with a Puma 6 slow to an unusable crawl.According to one engineer who spoke to El Reg on the issue, the flaw would be “trivial” to exploit in the wild, and would effectively render a targeted box useless for the duration of the attack.
