Those le32 sizes\nare never checked against the fetched blob, so a module reporting a\nsmall topology size but large section sizes makes the offsets point\npast the allocation, and parsing reads out of bounds.\n\nReject a topology whose section sizes do not fit within the fetched\nsize before it is
