{"schema":"threatline.record/2","record":{"id":"CVE-2026-104036","aliases":[],"summary":"Sssd: sssd: denial of service via out-of-bounds write in nfs idmap plugin","details":"A flaw was found in SSSD's NFS idmap plugin. When retrieving cached user or group names, the plugin detects if an entry exceeds the destination buffer size but fails to abort before copying data. A local attacker can trigger this vulnerability by requesting identity lookups that resolve to oversized cached entries, resulting in an out-of-bounds write. This flaw primarily leads to a Denial of Service (DoS) by crashing the identity mapping service, and may also corrupt adjacent process memory.","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-2026-104036","source_modified_at":"2026-10-16T10:57:37.848Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104036","source_modified_at":"2026-10-16T10:57:37.848Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 6","vendor":"Red Hat","versions":[],"defaultStatus":"unknown"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104036","source_modified_at":"2026-10-16T10:57:37.848Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 7","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104036","source_modified_at":"2026-10-16T10:57:37.848Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 8","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104036","source_modified_at":"2026-10-16T10:57:37.848Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104036","source_modified_at":"2026-10-16T10:57:37.848Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat OpenShift Container Platform 4","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104036","source_modified_at":"2026-10-16T10:57:37.848Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat OpenShift Container Platform 4","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":5.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00089,"percentile":0.00374,"score_date":"2026-10-23"},"published_at":"2026-10-06T00:12:20.485Z","modified_at":"2026-10-16T10:57:37.848Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104036","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T10:57:37.848Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104036","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-2026-104036","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2479057","tags":["issue-tracking","x_refsource_REDHAT"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-06T13:01:12.207991Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-16T10:57:37.848Z","content_hash":"d6526d82f5c99129a2796b021378e3970ecabd89c000f10fee0a57de72203085"}}
