Severity ?
4.7 (Medium) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
With its original introduction, GNTTAB_cache_flush was made available uniformly. XSA-232 (CVE-2017-14318) then covered an omitted NULL pointer check, yet the addition of that check failed to adjust the subsequent error path. That error path fails to drop a page reference in case the specified page is owned by a special system domain (DOM_IO and DOM_COW are system domains which can have memory pages assigned to them.)
