My personal favorite is the UEFI variable bugs that brick laptops. I think many of them are trivial to exploit even under Windows.

- geofft 10y agoDon't you need root access for those? They're awful bugs, yes, but being able to semi-permanently brick a laptop from privileged userspace isn't super surprising. If you can reflash the firmware without the firmware checking signatures on updates, you're done.
- yuhong 10y agoIt is trivial for any malware to do though, without even needing a kernel driver. I can see ransomware trying for example.
