{"id":"CVE-2026-42199","summary":"Grid: Integer Overflow in Grid::expand_rows Leads to Safe-API Undefined Behavior","details":"Grid is a data structure grid for rust. From version 0.17.0 to before version 1.0.1, an integer overflow in Grid::expand_rows() can corrupt the relationship between the grid’s logical dimensions and its backing storage. After the internal invariant is broken, the safe API get() may invoke get_unchecked() with an invalid index, resulting in Undefined Behavior. This issue has been patched in version 1.0.1.","aliases":["GHSA-38c5-483c-4qqp"],"modified":"2026-07-08T08:09:33.104965412Z","published":"2026-05-08T21:15:16.561Z","related":["CGA-mh2w-hpgg-2525"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-190"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42199.json"},"references":[{"type":"WEB","url":"https://github.com/becheran/grid/releases/tag/v1.0.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42199.json"},{"type":"ADVISORY","url":"https://github.com/becheran/grid/security/advisories/GHSA-38c5-483c-4qqp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42199"},{"type":"FIX","url":"https://github.com/becheran/grid/commit/be213bd3528727148bef2d523c89e95d1fd9c072"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/becheran/grid","events":[{"introduced":"c6288f165edb4f7f082703150148ef7e87d5c1cb"},{"fixed":"8caa81908f77d898c9b9c764b374d61f61cd6a20"}],"database_specific":{"extracted_events":[{"introduced":"0.17.0"},{"fixed":"1.0.1"}],"source":"AFFECTED_FIELD"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-42199.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
