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.","epss":{"date":"2026-11-02","percentile":0.1076,"score":0.00207},"exploits":[],"kev":null,"metrics":[{"score":7.1,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","version":"3.1"}],"modifiedAt":1793652332373,"publishedAt":1792714594250,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-115486"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2556267"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"Keep iscsiuio-managed interfaces on trusted L2 segments only.
