Juergen Gross 31185df7e2 xen/netfront: don't use gnttab_query_foreign_access() for mapped status ... It isn't enough to check whether a grant is still being in use by calling gnttab_query_foreign_access(), as a mapping could be realized by the other side just after having called that function. In case the call was done in preparation of revoking a grant it is better to do so via gnttab_end_foreign_access_ref() and check the success of that operation instead. This is CVE-2022-23037 / part of XSA-396.
