{"schema":"threatline.record/2","record":{"id":"CVE-2026-92150","aliases":["GHSA-2mh6-f7jj-6c93"],"summary":"F´: GenericHub Malformed Buffer 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, Svc::GenericHub fromBufferDriver_handler deserialization is vulnerable because the receive handler uses FW_ASSERT for externally influenced deserialization status and type validation and permits a command payload size subtraction to underflow. When an unauthenticated inter-processor hub peer sends a truncated buffer, an invalid HubType, or a header-only command-dispatch payload, malformed hub traffic aborts or resets the 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-2026-92150","source_modified_at":"2026-10-20T01:43:37.467Z","fetched_at":"2026-10-23T18:45:31.882637Z","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":0.00466,"percentile":0.39389,"score_date":"2026-10-23"},"published_at":"2026-10-14T17:18:29.342Z","modified_at":"2026-10-20T01:43:37.467Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92150","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T01:43:37.467Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92150","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-2mh6-f7jj-6c93","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/pull/4929","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/commit/b56b53634fd4251ae84919f22dcff829ef9e0986","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":"poc","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-20T01:43:05.787918Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T01:43:37.467Z","content_hash":"57263dbf14579939106ff86ca988c5c70f964ab08e356ef2ac1a4dd0e9c64f98"}}
