alt Hacker NewsIt's not a big deal because the Ars Technica summarisation is wrong. You can (and enterprise controllers do in fact) tie IPs and MACs to association IDs (8bit number per client+BSS) and thus prevent this kind of spoofing. I haven't had time to read the paper yet to check what it says on this.
Also client isolation is not considered "needed" in home/SOHO networks because this kind of attack is kinda assumed out of scope; it's not even tried to address this. "If you give people access to your wifi, they can fuck with your wifi devices." This should probably be communicated more clearly, but any claims on this attack re. home networks are junk.

What can you even do on the local network these days? Most everything is encrypted before it leaves the device. I guess you could cast stuff to the TV.
This is mostly accurate, to clarify the association IDs tie into what VLANs will be assigned and that does block all of the injection/MITM attacks. This also assumes that the VLAN segments are truly isolated from one another, as in they do not route traffic between each other by default including for broadcast and multicast traffic.
However client isolation should be a tool people have at their disposal. Consider the need for people to buy cloud IOT devices and throw them on a guest network (https://arstechnica.com/security/2024/09/massive-china-state...). It's also about keeping web-browsers away from these devices during regular use, because there are paths for malicious web pages to break into IOT devices.
