{"id":"CVE-2026-92160","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.","aliases":["GHSA-8r3j-ghrh-55mw"],"modified":"2026-10-15T02:49:35.054384250Z","published":"2026-10-14T17:20:36.334Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-190","CWE-617"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92160.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92160.json"},{"type":"FIX","url":"https://github.com/nasa/fprime/commit/33fe2a4fe3fd5ff1b14985669fbad09f070e9914"},{"type":"FIX","url":"https://github.com/nasa/fprime/commit/95eeb5cfb44e5609eff0887f0e11e640cdacef6b"},{"type":"FIX","url":"https://github.com/nasa/fprime/pull/5565"},{"type":"WEB","url":"https://github.com/nasa/fprime/releases/tag/v4.3.0"},{"type":"ADVISORY","url":"https://github.com/nasa/fprime/security/advisories/GHSA-8r3j-ghrh-55mw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92160"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nasa/fprime","events":[{"introduced":"0"},{"fixed":"7d8f579f159d2f7c2d4984d92828575e37f87fa6"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.3.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v4.3.0b1","v4.3.0a1","v4.2.0","v4.2.0a1","v4.1.1","v4.1.0","v4.0.1a1","v4.0.0a3","v4.0.0","v4.0.0a2","v4.0.0a1","v3.6.0","v3.5.1","v3.5.0","v3.4.3","v3.4.2","v3.4.1","v3.4.0","v3.3.2","v3.3.1","v3.3.0","v3.2.0","v3.1.1","v3.1.0","v3.0.0","NASA-v1.5.3","NASA-v1.5.2","NASA-v1.5.1","NASA-v1.5.0","NASA-v1.3.1","NASA-v1.00"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92160.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
