{"id":"CVE-2026-92155","summary":"F´: FileUplink Unknown Packet Type Assertion DoS","details":"F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. 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.","aliases":["GHSA-3534-8qg7-6cf5"],"modified":"2026-10-15T02:49:35.053471854Z","published":"2026-10-14T17:19:20.560Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92155.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-617"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92155.json"},{"type":"FIX","url":"https://github.com/nasa/fprime/commit/cacdd555456bd83ab395b521d56c0330470ea798"},{"type":"FIX","url":"https://github.com/nasa/fprime/pull/4919"},{"type":"WEB","url":"https://github.com/nasa/fprime/releases/tag/v4.2.0"},{"type":"ADVISORY","url":"https://github.com/nasa/fprime/security/advisories/GHSA-3534-8qg7-6cf5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92155"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nasa/fprime","events":[{"introduced":"0"},{"fixed":"f972bed2c56b1c497e70c6e7b1da7593e28f463b"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"4.2.0"}]}}],"versions":["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-2026-92155.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
