Yep, drivers, in general, are screwed. 🙂 Certified Windows drivers merely mean the drivers passed some basic tests. There are lots of gaps in how drivers are tested on Windows. (If Microsoft has open-sourced these tests, it would be helpful for researchers to find coverage gaps.) The UEFI SCTs are a minimum bar at feature testing, and have no security tests …and CHIPSEC only helps with security testing on Intel systems, not AMD nor ARM vendors. Does Linux have any equivalent tests for drivers, last time I looked into the LTP and some related projects it did not. Does Apple have tests like this for drivers?
