Thanks. That explains a lot of what I didn't think was right regarding the almost simultaneous failures.
I don't write kernel code at all for a living. But, I do understand the rationale behind it, and it seems to me this doesn't fit that expectation. Now, it's a lot of hypothetical. But if I were writing this software, any processing of these files would happen in userspace. This would mean that any rejection of bad/badly formatted data, or indeed if it managed to crash the processor it would just be an app crash.
The general rule I've always heard is that you want to keep the minimum required work in the kernel code. So I think processing/rejection should have been happening in userspace (and perhaps even using code written in a higher level language with better memory protections etc) and then a parsed and validated set of data would be passed to the kernel code for actioning.
But, I admit I'm observing from the outside, and it could be nothing like this. But, on the face of it, it does seem to me like they were processing too much in the kernel code.
