Prior to 4.2.0, Svc::FileUplink handleDataPacket offset and size validation is vulnerable because the component checks byteOffset plus dataSize with wrapping U32 arithmetic and then seeks to the large attacker-controlled offset before writing. When a file-uplink DATA packet supplies a byteOffset and dataSize whose unsigned sum wraps below the declared file size, data can be written beyond the declared upload size, causing file integrity loss and potentially large sparse-file growth or resource exhaustion. This issue is fixed in version 4.2.0.","state":0,"publishedAt":"2026-10-14T17:17:20.331+00:00","modifiedAt":"2026-10-15T18:55:39.17+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:L/UI:N/S:U/C:N/I:H/A:H","score":8.1,"severity":"HIGH"}],"references":["https://github.com/nasa/fprime/security/advisories/GHSA-wx8q-q5gx-f54p","https://github.com/nasa/fprime/pull/4919","https://github.com/nasa/fprime/commit/cacdd555456bd83ab395b521d56c0330470ea798"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92154","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92154","identifiers":["CVE-2026-92154"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
