Details In the unique reclaim path of BytesMut::reserve, the condition rs if vcapacity = newcap + offset uses an unchecked addition. When newcap + offset overflows usize in release builds, this condition may incorrectly pass, causing self.cap to be set to a value that exceeds the actual allocated...
