{"id":"DEBIAN-CVE-2024-27007","details":"In the Linux kernel, the following vulnerability has been resolved:  userfaultfd: change src_folio after ensuring it's unpinned in UFFDIO_MOVE  Commit d7a08838ab74 (\"mm: userfaultfd: fix unexpected change to src_folio when UFFDIO_MOVE fails\") moved the src_folio-\u003e{mapping, index} changing to after clearing the page-table and ensuring that it's not pinned.  This avoids failure of swapout+migration and possibly memory corruption.  However, the commit missed fixing it in the huge-page case.","modified":"2026-09-15T09:03:06.157374313Z","published":"2024-05-01T06:15:19.180Z","upstream":["CVE-2024-27007"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-27007"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.8.9-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-27007.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.8.9-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-27007.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
