{"id":"CVE-2026-92157","published":"2026-10-14T18:19:35.073","lastModified":"2026-10-15T14:45:10.783","description":"F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::FileDownlink SendPartial range validation is vulnerable because unchecked startOffset plus length arithmetic bypasses the range check and stores a wrapped m_endOffset that is inconsistent with m_byteOffset. When an existing source file is larger than a valid startOffset and a SendPartial command supplies a length whose U32 sum with that offset wraps below the file size, under standard F Prime assertion handling, the first data-packet transition reaches FW_ASSERT and aborts or resets the process, causing denial of service. This issue is fixed in version 4.3.0.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-190","CWE-617"],"vendors":[],"products":[],"references":[{"url":"https://github.com/nasa/fprime/commit/33fe2a4fe3fd5ff1b14985669fbad09f070e9914","tags":[]},{"url":"https://github.com/nasa/fprime/commit/95eeb5cfb44e5609eff0887f0e11e640cdacef6b","tags":[]},{"url":"https://github.com/nasa/fprime/pull/5565","tags":[]},{"url":"https://github.com/nasa/fprime/releases/tag/v4.3.0","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-hcmw-g425-8h9g","tags":[]}],"exploitRefs":[{"url":"https://github.com/nasa/fprime/commit/33fe2a4fe3fd5ff1b14985669fbad09f070e9914","tags":[]},{"url":"https://github.com/nasa/fprime/commit/95eeb5cfb44e5609eff0887f0e11e640cdacef6b","tags":[]},{"url":"https://github.com/nasa/fprime/pull/5565","tags":[]},{"url":"https://github.com/nasa/fprime/releases/tag/v4.3.0","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-hcmw-g425-8h9g","tags":[]}],"hasPoc":true,"ai":null}
