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.","state":0,"publishedAt":"2026-10-14T17:19:20.56+00:00","modifiedAt":"2026-10-15T15:07:29.42+00:00","affected":[{"ecosystem":"Vendor product","name":"fprime","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nasa\",\n                    \"product\": \"fprime\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.2.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/nasa/fprime/security/advisories/GHSA-3534-8qg7-6cf5","https://github.com/nasa/fprime/pull/4919","https://github.com/nasa/fprime/commit/cacdd555456bd83ab395b521d56c0330470ea798","https://github.com/nasa/fprime/releases/tag/v4.2.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92155","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92155","identifiers":["CVE-2026-92155"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
