{"schema":"threatline.record/2","record":{"id":"CVE-2026-92823","aliases":[],"summary":"Libmodulemd: libmodulemd: missing decompressed-size limit when parsing compressed yaml","details":"A flaw was found in libmodulemd. In builds with rpmio support enabled, compressed modulemd YAML is decompressed through a custom read handler that does not enforce a cumulative decompressed-size limit before parsing. An attacker who can supply a highly compressible compressed YAML file can cause excessive CPU and memory consumption, resulting in a denial of service.","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-2026-92823","source_modified_at":"2026-10-21T15:49:05.380Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92823","source_modified_at":"2026-10-21T15:49:05.380Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Red Hat Enterprise Linux 8","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92823","source_modified_at":"2026-10-21T15:49:05.380Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92823","source_modified_at":"2026-10-21T15:49:05.380Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Red Hat Hardened Images","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92823","source_modified_at":"2026-10-21T15:49:05.380Z","fetched_at":"2026-10-23T18:45:31.882637Z","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-2026-92823","source_modified_at":"2026-10-21T15:49:05.380Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Red Hat OpenShift Container Platform 4","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":6.2,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00117,"percentile":0.01594,"score_date":"2026-10-23"},"published_at":"2026-10-21T03:18:37.968Z","modified_at":"2026-10-21T15:49:05.380Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92823","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T15:49:05.380Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92823","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-2026-92823","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2478703","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":"2026-10-21T15:00:02.575963Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-21T15:49:05.380Z","content_hash":"e3a36fab9b186ed42175996fd8552a376977f31c1442dc3559a57ebc9c8a6021"}}
