{"id":"CVE-2026-92159","summary":"F´: TlmPacketizer copies oversized telemetry past configured channel slots and emits corrupted packetized telemetry","details":"F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::TlmPacketizer TlmRecv_handler fixed-slot copy TlmRecv_handler copies val.getSize bytes into entry.channelSize storage without confirming that the runtime value fits. When a telemetry update for a configured channel carries a serialized value larger than that channel fixed slot, the copy overwrites adjacent channel fields and causes corrupted packetized telemetry to be emitted. This issue is fixed in version 4.3.0.","aliases":["GHSA-grrq-8rmr-xf83"],"modified":"2026-10-15T02:49:35.086528395Z","published":"2026-10-14T17:12:47.065Z","database_specific":{"cwe_ids":["CWE-130","CWE-805"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92159.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92159.json"},{"type":"FIX","url":"https://github.com/nasa/fprime/commit/048fe04062b91be7af138df7e09cdd15812dde96"},{"type":"FIX","url":"https://github.com/nasa/fprime/commit/7eacd551aaf6d9a21e347ac2c8d827ca15ee5755"},{"type":"FIX","url":"https://github.com/nasa/fprime/pull/4878"},{"type":"WEB","url":"https://github.com/nasa/fprime/releases/tag/v4.3.0a1"},{"type":"ADVISORY","url":"https://github.com/nasa/fprime/security/advisories/GHSA-grrq-8rmr-xf83"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92159"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nasa/fprime","events":[{"introduced":"0"},{"fixed":"7d8f579f159d2f7c2d4984d92828575e37f87fa6"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"4.3.0"}]}}],"versions":["v4.3.0b1","v4.3.0a1","v4.2.0","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-2026-92159.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
