You are thinking about the one that fried some googler laptop.
This has NOTHING to do with it.
it will continue to fry your computer. This has to do with the fact that the cable itself now has a processor, like the lightning cable. or a usb hub.
This code, which they will force on the kernel upstream i bet, will make sure that the image running there is from some trusted vendor. Something like calling an API getVendorID and then the chip on the cable would return "copyrighted string ABC" so that they can sue manufacturers not paying the USB group fees, while not protecting you at all.
Now, if they had a tester device on the other end and they could try to detect any time skew from data going from one end to another, they could in theory detect man-in-middle attacks, which is all a cable can do... but i doubt that is the case.
