The IPv6 Neighbor Discovery handler accesses link-layer address options at a fixed offset without verifying the packet contains them. Additionally, the ARP table is updated unconditionally with attacker-controlled addresses from the packet headers. An attacker on the same network segment can send a minimal Neighbor Advertisement to poison the ARP table and redirect network traffic.","state":0,"publishedAt":"2026-10-23T00:16:34.25+00:00","modifiedAt":"2026-10-26T14:30:55.948+00:00","affected":[{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"iscsi-initiator-utils","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 10\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"iscsi-initiator-utils\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:10\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"iscsi-initiator-utils","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 6\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"iscsi-initiator-utils\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:6\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"iscsi-initiator-utils","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 7\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"iscsi-initiator-utils\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:7\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"iscsi-initiator-utils","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 8\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"iscsi-initiator-utils\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:8\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"iscsi-initiator-utils","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 9\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"iscsi-initiator-utils\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:9\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","score":7.1,"severity":"HIGH"}],"references":["https://access.redhat.com/security/cve/CVE-2026-115486","https://bugzilla.redhat.com/show_bug.cgi?id=2556267"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-115486","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-115486","identifiers":["CVE-2026-115486"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
