{"id":"CVE-2026-5476","state":"PUBLISHED","title":"NASA cFS cfe_tbl_passthru_codec.c CFE_TBL_ValidateCodecLoadSize integer overflow","description":"A vulnerability was identified in NASA cFS up to 7.0.0 on 32-bit. Affected is the function CFE_TBL_ValidateCodecLoadSize of the file cfe/modules/tbl/fsw/src/cfe_tbl_passthru_codec.c. The manipulation leads to integer overflow. The complexity of an attack is rather high. The exploitability is told to be difficult. A fix is planned for the upcoming version milestone of the project.","publishedAt":"2026-04-03T17:30:12.629Z","updatedAt":"2026-04-04T03:20:03.080Z","severity":{"score":2.1,"label":"Low","version":"4.0","vector":"CVSS:4.0/AV:A/AC:H/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:X","source":"VulDB"},"assigner":"VulDB","products":["NASA cFS"],"affected":[{"vendor":"NASA","product":"cFS","versions":[{"version":"7.0","status":"affected"}],"cpes":["cpe:2.3:a:nasa:cfs:*:*:*:*:*:*:*:*"]}],"references":["https://vuldb.com/vuln/355080","https://vuldb.com/vuln/355080/cti","https://vuldb.com/submit/781971","https://github.com/nasa/cFS/issues/954","https://github.com/nasa/cFS/"],"weaknesses":["CWE-190","CWE-189"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/5xxx/CVE-2026-5476.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-5476","state":"PUBLISHED","datePublished":"2026-04-03T17:30:12.629Z","dateUpdated":"2026-04-04T03:20:03.080Z","assignerShortName":"VulDB","assignerOrgId":"1af790b2-7ee1-4545-860a-a788eba489b5","dateReserved":"2026-04-03T07:51:24.742Z"},"containers":{"cna":{"title":"NASA cFS cfe_tbl_passthru_codec.c CFE_TBL_ValidateCodecLoadSize integer overflow","descriptions":[{"lang":"en","value":"A vulnerability was identified in NASA cFS up to 7.0.0 on 32-bit.
