{"id":"UBUNTU-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leading to a remote denial-of-service.","modified":"2026-02-04T04:37:55.455804Z","published":"2018-09-18T00:00:00Z","withdrawn":"2025-06-23T15:53:14Z","related":["CVE-2018-14641"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-14641"},{"type":"REPORT","url":"https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5d407b071dc369c26a38398326ee2be53651cfe4"},{"type":"REPORT","url":"https://www.openwall.com/lists/oss-security/2018/09/18/1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-14641"}],"affected":[{"package":{"name":"linux-flo","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/linux-flo@3.4.0-5.23?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.0-5.19","3.4.0-5.22","3.4.0-5.23"],"ecosystem_specific":{"ubuntu_priority":"high"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-14641.json"}},{"package":{"name":"linux-goldfish","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/linux-goldfish@3.4.0-4.27?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.0-4.24","3.4.0-4.26","3.4.0-4.27"],"ecosystem_specific":{"ubuntu_priority":"high"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-14641.json"}},{"package":{"name":"linux-mako","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/linux-mako@3.4.0-7.44?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.0-7.39","3.4.0-7.40","3.4.0-7.41","3.4.0-7.44"],"ecosystem_specific":{"ubuntu_priority":"high"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-14641.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
