{"identifier":"CVE-2026-93008","cve":{"id":"CVE-2026-93008","description":"A flaw was found in dnsmasq. When following a CNAME in a DNS response, the resolver can cache records for the CNAME target without checking that those records belong to the responding server's authorized zone. In split-DNS deployments that send some domains to a specific upstream, an attacker who controls that upstream can inject cache entries for unrelated names. Later clients may then receive attacker-chosen addresses for those names.","published":"2026-10-29T13:17:16.053000+00:00","modified":"2026-10-30T01:16:48.057000+00:00","status":"Awaiting Analysis","score":6.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N","cvss_version":"3.1","affected":[],"weaknesses":["CWE-345"],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-93008","source":"secalert@redhat.com"},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2536079","source":"secalert@redhat.com"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"secalert@redhat.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N","baseScore":6.8,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":2.2,"impactScore":4.0}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-30T02:16:49.960903+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence.","Fresh EPSS data is unavailable; missing values are not zero."]},"epss":null,"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"access.redhat.com","source_url":"https://access.redhat.com/security/cve/CVE-2026-93008","investigate_url":"https://investigate.aeglixmind.com/#access.redhat.com"},{"domain":"bugzilla.redhat.com","source_url":"https://bugzilla.redhat.com/show_bug.cgi?id=2536079","investigate_url":"https://investigate.aeglixmind.com/#bugzilla.redhat.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-93008","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-93008","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-93008","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
