{"schema":"threatline.record/2","record":{"id":"CVE-2026-115486","aliases":[],"summary":"Open-iscsi: open-iscsi: ipv6 neighbor discovery missing option length validation in iscsiuio allows arp table poisoning","details":"A flaw was found in the iscsiuio component of open-iscsi. 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.","categories":["Operating systems"],"product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115486","source_modified_at":"2026-10-23T00:16:34.250Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115486","source_modified_at":"2026-10-23T00:16:34.250Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Red Hat Enterprise Linux 6","vendor":"Red Hat","versions":[],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115486","source_modified_at":"2026-10-23T00:16:34.250Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Red Hat Enterprise Linux 7","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115486","source_modified_at":"2026-10-23T00:16:34.250Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Red Hat Enterprise Linux 8","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115486","source_modified_at":"2026-10-23T00:16:34.250Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00206,"percentile":0.10202,"score_date":"2026-10-23"},"published_at":"2026-10-23T00:16:34.250Z","modified_at":"2026-10-23T00:16:34.250Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-115486","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T00:16:34.250Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-115486","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-115486","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2556267","tags":["issue-tracking","x_refsource_REDHAT"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-23T00:16:34.250Z","content_hash":"0f161a960caa161bf448b5dde6cbdf6bbeef2421eb28c598e125774ae7972bc6"}}
