How to fix?

Upgrade SLES:15.5 xen-tools to version 4.17.7_02-150500.3.82.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xen-tools package and not the xen-tools package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

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.)
