The first function ("validateChunk") now makes sure that:
chunk + currentChunkSize >= currentChunk
when checking that the current chunk doesn't overlap with either the previous or next one.
The second function ("Kern::ControlMemory"), aside from other small changes, now makes additional checks on the previously allocated memory chunk; the code for that is now:
if(chunkSizeInPages >= regionSize >> 12 || chunk < regionBase || chunk + chunkSize < chunk || chunk + chunkSize > regionBase + regionSize) panic;
The third function ("insertChunk") now makes the following checks:
if(chunkSizeInPages >= regionSize >> 12 || regionBase + regionSize < chunk + chunkSize) panic;
// ...
if(leftChunk && leftChunk + leftChunkSize <= leftChunk) panic;
