Grant copying code made an implication that any grant pin would be accompanied by a suitable page reference. Other portions of code, however, did not match up with that assumption. When such a grant copy operation is being done on a grant of a dying domain, the assumption turns out wrong. A malicious guest administrator can cause hypervisor memory corruption, most likely resulting in host crash and a Denial of Service. Privilege escalation and information leaks cannot be ruled out.","published":"2017-10-30T14:29:01.000Z","lastModified":"2026-06-17T01:07:57.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":9.1,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H"},"cwe":["CWE-119","CWE-200"],"affected":["xen/xen"],"epss":{"score":0.0283,"percentile":0.86546,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (2.83%).
