{"schema":"threatline.record/2","record":{"id":"CVE-2026-92160","aliases":["GHSA-8r3j-ghrh-55mw"],"summary":"F´: SendPartial Integer Overflow Leading to Assertion DoS","details":"F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::FileDownlink SendPartial range validation is vulnerable because the wrapping sum bypasses file-range validation, becomes m_endOffset, and leaves m_byteOffset greater than the wrapped end offset. When an existing source file is larger than the supplied startOffset and a caller able to issue SendPartial supplies a length whose U32 sum with that offset wraps, the first data-packet send reaches FW_ASSERT and aborts or resets the process, causing denial of service. This issue is fixed in version 4.3.0.","categories":["Unclassified"],"product":"fprime","vendor":"nasa","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92160","source_modified_at":"2026-10-15T15:07:20.709Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"fprime","vendor":"nasa","versions":[{"status":"affected","version":"< 4.3.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/nasa/fprime/security/advisories/GHSA-8r3j-ghrh-55mw","source_modified_at":"2026-09-15T23:56:23Z","fetched_at":"2026-10-24T18:03:20.872036Z","package":{"ecosystem":"","name":"F´ / fprime "},"range":"< 4.2.2"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/nasa/fprime/security/advisories/GHSA-8r3j-ghrh-55mw","source_modified_at":"2026-09-15T23:56:23Z","fetched_at":"2026-10-24T18:03:20.872036Z","package":{"ecosystem":"","name":"F´ / fprime "},"version":"4.3"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00339,"percentile":0.26119,"score_date":"2026-10-23"},"published_at":"2026-10-14T17:20:36.334Z","modified_at":"2026-10-15T15:07:20.709Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92160","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T15:07:20.709Z"},{"source":"GitHub Advisory Database","url":"https://github.com/nasa/fprime/security/advisories/GHSA-8r3j-ghrh-55mw","fetched_at":"2026-10-24T18:03:20.872036Z","source_modified_at":"2026-09-15T23:56:23Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92160","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/nasa/fprime/security/advisories/GHSA-8r3j-ghrh-55mw","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/pull/5565","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/commit/33fe2a4fe3fd5ff1b14985669fbad09f070e9914","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/commit/95eeb5cfb44e5609eff0887f0e11e640cdacef6b","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/nasa/fprime/releases/tag/v4.3.0","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":"no","technical_impact":"partial","assessed_at":"2026-10-15T13:52:11.338963Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T15:07:20.709Z","content_hash":"06417e9fb61ebd2a1e99421d5f9451ab313123b32838c4e758098c379fe251ad"}}
