{"id":"CVE-2018-14641","details":"A security flaw was found in the ip_frag_reasm() function in net/ipv4/ip_fragment.c in the Linux kernel from 4.19-rc1 to 4.19-rc3 inclusive, which can cause a later system crash in ip_do_fragment(). With certain non-default, but non-rare, configuration of a victim host, an attacker can trigger this crash remotely, thus leading to a remote denial-of-service.","modified":"2026-03-15T22:19:08.018802Z","published":"2018-09-18T13:29:00.360Z","related":["MGASA-2018-0391","MGASA-2018-0418","MGASA-2018-0419"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:2948"},{"type":"FIX","url":"https://seclists.org/oss-sec/2018/q3/248"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14641"},{"type":"FIX","url":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5d407b071dc369c26a38398326ee2be53651cfe4"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"4.19-rc1"}]},{"events":[{"introduced":"0"},{"last_affected":"4.19-rc2"}]},{"events":[{"introduced":"0"},{"last_affected":"4.19-rc3"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-14641.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
