This does feel like a decent anti exploitation mechanism that I'd think any reasonable OS should be doing these days.
Is there an easy way to check - other than write some code that tries to access the null page?
Not this version.
FPT_NULL_EXT.1.1 The OS shall allocation the first 4k of memory starting at address zero and mark the memory as read only.
App Note: By having the OS allocate the first 4k of memory as read only, it will prevent any malicious code from having the chance to allocate that memory and possible trigger a null dereference attack.
