Another two months have passed and upstream is still apparently ignoring this. Frankly, if you can make kernel load corrupted firmware file, I suspect the effect you get by scribbling over kernel memory on top of it isn't that interesting so I guess let's close this as WONTFIX. Reassigning back to security team.
