{"id":"CVE-2022-1158","details":"A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and potentially corrupt the kernel, resulting in a denial of service condition.","modified":"2026-03-14T01:39:31.132519Z","published":"2022-08-05T17:15:08.017Z","related":["MGASA-2022-0154","MGASA-2022-0155","SUSE-SU-2022:1569-1","SUSE-SU-2022:1571-1","SUSE-SU-2022:1573-1","SUSE-SU-2022:1575-1","SUSE-SU-2022:1591-1","SUSE-SU-2022:1605-1","SUSE-SU-2022:1629-1","SUSE-SU-2022:1634-1","SUSE-SU-2022:1637-1","SUSE-SU-2022:1669-1","SUSE-SU-2022:1676-1","SUSE-SU-2022:1687-1","SUSE-SU-2022:2104-1"],"references":[{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20230214-0003/"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2069793"},{"type":"EVIDENCE","url":"https://www.openwall.com/lists/oss-security/2022/04/08/4"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-1158.json","unresolved_ranges":[{"events":[{"introduced":"5.2"},{"fixed":"5.4.189"}]},{"events":[{"introduced":"5.5"},{"fixed":"5.10.110"}]},{"events":[{"introduced":"5.11"},{"fixed":"5.15.33"}]},{"events":[{"introduced":"5.16"},{"fixed":"5.16.19"}]},{"events":[{"introduced":"5.17"},{"fixed":"5.17.2"}]},{"events":[{"introduced":"0"},{"last_affected":"36"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
