{"schemaVersion":3,"id":"CVE-2026-92154","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. 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.","dates":{"published":"2026-10-14T17:17:20.331Z","modified":"2026-10-15T18:55:39.170Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.1,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.1,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.1,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.0056,"percentile":0.45788,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-15T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.0056,"percentile":0.45788}],"last30":[{"date":"2026-10-15T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.0056,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.0056,"percentile":0.45788}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-190","name":"Integer Overflow or Wraparound","description":"The product performs a calculation that can\n         produce an integer overflow or wraparound when the logic\n         assumes that the resulting value will always be larger than\n         the original value.
