For this Channel File, yes. I don’t know what the failure rate is - this article mentions 40-70%, but there could well be a lot of variance between different companies’ machines.
The driver has presumably had this bug for some time, but they’ve never had a channel file trigger it before. I can’t find any good information on how they deploy these channel files other than that they push several changes per day. One would hope these are always run by a diverse set of test machines to validate there’s no impact to functionality but only they know the procedure there. It might vary based on how urgent a mitigation is or how invasive it’ll be - though they could just be winging it. It’d be interesting to find out exactly how this all went down.
I’m a bit OOTL on what exactly a channel file is, being a Linux person, or how it relates to a driver. Are they in userspace, then? That would make it slightly less insane they didn’t check it thoroughly before their Friday update.
I mean, even basic testing would have caught this. It’s not like it’s particularly infrequently triggered.
