Therefore Xen needs to cache the guest chosen index, and one of\nthe usages of the index didn't take the necessary locking to avoid\nconcurrent changes.  As a result, a guest could change the index after\nit being checked, causing a subsequent out-of-bound read access to the\ncontents of an array.",
