If a sufficient number of such requests are made, an OutOfMemoryException could occur, leading to a denial of service. The highest threat from this vulnerability is to system availability." ],

However, HTTP/2 is not enabled in such a configuration, and it is not possible to trigger the flaw in a supported setup. A future update may fix the code.",
