Parsing a symlink entry in an untrusted RPM package whose declared RPMTAG_LONGFILESIZES value is 0xFFFFFFFFFFFFFFFF causes an integer overflow in iterReadArchiveNext() that shrinks a buffer allocation to one byte, after which the payload's independently-controlled cpio filesize field is used to write attacker-controlled data past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package.","evidence":"cve:CVE-2026-95520","products":[{"name":{"value":"Red Hat Enterprise Linux 10","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"Red Hat Enterprise Linux 6","evidence":"/containers/cna/affected/1/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"Red Hat Enterprise Linux 7","evidence":"/containers/cna/affected/2/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"Red Hat Enterprise Linux 8","evidence":"/containers/cna/affected/3/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"Red Hat Enterprise Linux 9","evidence":"/containers/cna/affected/4/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"Red Hat Hardened Images","evidence":"/containers/cna/affected/5/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"high","structured":{"id":"CVE-2026-95520","aliases":["CVE-2026-95520"],"metrics":[{"other":{"type":"Red Hat severity rating","content":{"value":"Moderate","namespace":"https://access.redhat.com/security/updates/classification/"}}},{"format":"CVSS","cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.1,"attackVector":"LOCAL","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","integrityImpact":"HIGH","userInteraction":"REQUIRED","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"NONE","confidentialityImpact":"NONE"}}],"affected":[{"cpes":["cpe:/o:redhat:enterprise_linux:10"],"vendor":"Red Hat","product":"Red Hat Enterprise Linux 10","packageName":"rpm","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"affected"},{"cpes":["cpe:/o:redhat:enterprise_linux:6"],"vendor":"Red Hat","product":"Red Hat Enterprise Linux 6","packageName":"rpm","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"unaffected"},{"cpes":["cpe:/o:redhat:enterprise_linux:7"],"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","packageName":"rpm","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"unaffected"},{"cpes":["cpe:/o:redhat:enterprise_linux:8"],"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","packageName":"rpm","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"affected"},{"cpes":["cpe:/o:redhat:enterprise_linux:9"],"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","packageName":"rpm","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"affected"},{"cpes":["cpe:/a:redhat:hummingbird:1"],"vendor":"Red Hat","product":"Red Hat Hardened Images","packageName":"rpm","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"affected"}],"modified":"2026-09-29T13:19:42.202Z","provider":"cve","references":["https://access.redhat.com/security/cve/CVE-2026-95520","https://bugzilla.redhat.com/show_bug.cgi?id=2537809"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-95520","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-29T13:17:45.627559Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-29T13:19:42.202Z"}}],"cna":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-09-29T11:13:43.800Z"}}},"related_cves":[{"value":"CVE-2026-95520","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"},"priority":{"reasons":["publisher_severity"],"severity":"high","linked_cves":[],"fix_available":false,"known_exploited":false,"publisher_severity":"high"},"context_update":false,"detail_url":"/events/3446"}],"next_after":3446,"next_before":3446}
