It's not new - fault injection as a vulnerability class has existed since the beginning of computing, as a security bypass mechanism (clock glitching) since at least the 1990s, and crowbar voltage glitching like this has been widespread since at least the early 2000s. It's extraordinarily hard to defend against but mitigations are also improving rapidly; for example this attack only works on early Xbox One revisions where more advanced glitch protection wasn't enabled (although the author speculates that since the glitch protection can be disabled via software / a fuse state, one could glitch out the glitch protection).
