{"id":"CVE-2026-92156","published":"2026-10-14T18:19:34.920","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::EventManager loqQueue_internalInterfaceHandler packetization is vulnerable because EventManager accepts up to the framework LogBuffer maximum, but packet descriptor, event identifier, and time-tag metadata consume part of the larger ComBuffer and leave a smaller remaining budget for log arguments; serialization failure then reaches an assertion. When a deployment bridges events through GenericHub into EventManager and forwards a legal Fw::LogBuffer larger than EventManager remaining log-argument budget, under standard F Prime assertion handling, a legal bridged event payload 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-131","CWE-617"],"vendors":[],"products":[],"references":[{"url":"https://github.com/nasa/fprime/commit/7eacd551aaf6d9a21e347ac2c8d827ca15ee5755","tags":[]},{"url":"https://github.com/nasa/fprime/pull/5633","tags":[]},{"url":"https://github.com/nasa/fprime/releases/tag/v4.3.0","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-6fxx-mgfv-55g7","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-6fxx-mgfv-55g7","tags":[]}],"exploitRefs":[{"url":"https://github.com/nasa/fprime/commit/7eacd551aaf6d9a21e347ac2c8d827ca15ee5755","tags":[]},{"url":"https://github.com/nasa/fprime/pull/5633","tags":[]},{"url":"https://github.com/nasa/fprime/releases/tag/v4.3.0","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-6fxx-mgfv-55g7","tags":[]},{"url":"https://github.com/nasa/fprime/security/advisories/GHSA-6fxx-mgfv-55g7","tags":[]}],"hasPoc":true,"ai":null}
