{"id":"CVE-2017-15597","details":"An issue was discovered in Xen through 4.9.x. 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.","modified":"2026-03-12T22:35:38.185390Z","published":"2017-10-30T14:29:00.847Z","related":["SUSE-SU-2017:3115-1","SUSE-SU-2017:3178-1","SUSE-SU-2017:3212-1","SUSE-SU-2017:3236-1","SUSE-SU-2017:3239-1","SUSE-SU-2017:3242-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2018/10/msg00009.html"},{"type":"ADVISORY","url":"https://www.debian.org/security/2017/dsa-4050"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2017/10/24/3"},{"type":"REPORT","url":"http://www.securityfocus.com/bid/101564"},{"type":"REPORT","url":"http://www.securitytracker.com/id/1039653"},{"type":"REPORT","url":"https://support.citrix.com/article/CTX229057"},{"type":"FIX","url":"http://xenbits.xen.org/xsa/advisory-236.html"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"4.9.0"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2017-15597.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H"}]}
