Description
When the message size is large enough to be close to wrapping, adding the overhead to it can result in undetected wrapping. Similarly, if the number of messages multiplied by the size of each message buffer wraps, this is also undetected. Either condition results in an insufficiently small message buffer pool which may lead to an invalid memory access.
