{"schema":"threatline.record/2","record":{"id":"CVE-2026-92155","aliases":["GHSA-3534-8qg7-6cf5"],"summary":"F´: FileUplink Unknown Packet Type Assertion DoS","details":"F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.2.0, Fw::FilePacket deserialization used by Svc::FileUplink is vulnerable because Header deserialization casts the byte to the Type enum without validating its range and FilePacket::fromSerialBuffer reaches a default FW_ASSERT. When a network file packet contains an unknown file-packet type byte, the assertion aborts or resets the default Ref application process, causing denial of service. This issue is fixed in version 4.2.0.","categories":["Unclassified"],"product":"fprime","vendor":"nasa","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92155","source_modified_at":"2026-10-15T15:07:29.420Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"fprime","vendor":"nasa","versions":[{"version":"< 4.2.0","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00366,"percentile":0.29288,"score_date":"2026-10-23"},"published_at":"2026-10-14T17:19:20.560Z","modified_at":"2026-10-15T15:07:29.420Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92155","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T15:07:29.420Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92155","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/nasa/fprime/security/advisories/GHSA-3534-8qg7-6cf5","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/pull/4919","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/commit/cacdd555456bd83ab395b521d56c0330470ea798","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/releases/tag/v4.2.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-15T13:55:52.938459Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T15:07:29.420Z","content_hash":"5adc44e99228957acb7e89a0478c0679b06cfd3199ea82e8455f6f190ea65cf9"}}
