Disclosure of the details of a bug on 32-bit systems which may, in a rare edge case, cause the node to crash when receiving a pathological block. This bug would be extremely hard to exploit. A fix was released on October 10th 2025 in Bitcoin Core v30.0.
This issue is considered Low severity.

Details
Before writing a block to disk, Bitcoin Core checks that its size is within a normal range. This check would overflow on 32-bit systems for blocks over 1GB, and make the node crash when writing it to disk. Such a block cannot be sent using the BLOCK message, but could in theory be sent as a compact block if the victim node has a non-default large mempool which already contains 1GB of transactions. This would require the victim to have set their -maxmempool option to a value greater than 3GB, while 32-bit systems may have at most 4GiB of memory.
This issue was indirectly prevented by capping the maximum value of the -maxmempool setting on 32-bit systems.
