the median contributor to Linux is an overworked driver developer (who may not have much software development experience at all) who is throwing stuff at the wall to try to get something to work on their machine, often with inaccurate or incomplete documentation (even or especially if they work for the company making the hardware they are writing a driver for). It's a swamp of subpar C code once you get outside the core subsystems. And yes, there are a lot of people throwing various analysis tools at the kernel to try to catch these, but the tools are quite noisy, and proper testing is hard without the relevant hardware.
