A comment on New fuzzing tool finds USB bugs in Linux, Windows, macOS, and FreeBSD. Parent comment
To be fair, dereferencing NULL ended up as a vulnerability due to
1. the optimiser removing the subsequent NULL check, and
2. the zero page being mapped.
While 1. may happen, depending on how sophisticated the compiler is, 2. was already a security issue and is 'almost always' not the case.
