{"identifier":"CVE-2026-94640","cve":{"id":"CVE-2026-94640","description":"A flaw was found in rpcbind. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by sending a large number of unique requests. The rpcbind service records previously unseen RPC (Remote Procedure Call) statistics in unbounded in-memory lists, leading to persistent memory growth and increased CPU usage. This can degrade or exhaust service availability.","published":"2026-09-22T16:18:18.143000+00:00","modified":"2026-10-28T11:17:28.380000+00:00","status":"Awaiting Analysis","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_version":"3.1","affected":[],"weaknesses":["CWE-400"],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:83561","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:83562","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:83563","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/errata/RHSA-2026:89197","source":"secalert@redhat.com"},{"url":"https://access.redhat.com/security/cve/CVE-2026-94640","source":"secalert@redhat.com"},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2462960","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:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-09-25T23:39:21.046890Z","id":"CVE-2026-94640","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T13:50:33.125966+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."]},"epss":{"probability":0.0046,"percentile":0.39853,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"access.redhat.com","source_url":"https://access.redhat.com/errata/RHSA-2026:83561","investigate_url":"https://investigate.aeglixmind.com/#access.redhat.com"},{"domain":"bugzilla.redhat.com","source_url":"https://bugzilla.redhat.com/show_bug.cgi?id=2462960","investigate_url":"https://investigate.aeglixmind.com/#bugzilla.redhat.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-94640","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-94640","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-94640","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
