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.","state":0,"publishedAt":"2026-10-14T17:10:13.076+00:00","modifiedAt":"2026-10-14T17:52:06.724+00:00","affected":[{"ecosystem":"Vendor product","name":"fprime","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nasa\",\n                    \"product\": \"fprime\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 4.3.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/nasa/fprime/security/advisories/GHSA-6fxx-mgfv-55g7","https://github.com/nasa/fprime/pull/5633","https://github.com/nasa/fprime/commit/7eacd551aaf6d9a21e347ac2c8d827ca15ee5755","https://github.com/nasa/fprime/releases/tag/v4.3.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92156","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92156","identifiers":["CVE-2026-92156"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
