{"schemaVersion":3,"id":"CVE-2026-92158","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::FpySequencer STORE directive stack write validation the bounds check adds attacker-controlled offset and size before memcpy, allowing integer wraparound to make an out-of-range destination appear valid. When a sequence-controlled STORE directive supplies a stack offset and size whose U32 sum wraps, memcpy can write outside the sequencer stack, causing memory corruption, denial of service, and potentially code execution. This issue is fixed in version 4.2.0.","dates":{"published":"2026-10-14T17:14:17.994Z","modified":"2026-10-14T17:14:17.994Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.2,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.2,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.2,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00747,"percentile":0.54085,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-15T00:00:00.000Z","score":0.00747,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00747,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00747,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00747,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00747,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00747,"percentile":0.54085}],"last30":[{"date":"2026-10-15T00:00:00.000Z","score":0.00747,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00747,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00747,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00747,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00747,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00747,"percentile":0.54085}]},"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.
