{"id":"CVE-2019-9857","details":"In the Linux kernel through 5.0.2, the function inotify_update_existing_watch() in fs/notify/inotify/inotify_user.c neglects to call fsnotify_put_mark() with IN_MASK_CREATE after fsnotify_find_mark(), which will cause a memory leak (aka refcount leak). Finally, this will cause a denial of service.","modified":"2026-03-12T23:33:52.516981Z","published":"2019-03-21T16:01:17.377Z","references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NXLZ2V2ES37A3J7DMK4MZYIWV2LEZFLM/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PPH3B7FJOMWD5JWUPZKB6T44KNT4PX2L/"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/107527"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20190404-0002/"},{"type":"FIX","url":"https://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs.git/commit/?h=fsnotify&id=62c9d2674b31d4c8a674bee86b7edc6da2803aea"},{"type":"FIX","url":"https://patchwork.kernel.org/patch/10836283/"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"5.0.2"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2019-9857.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
