A remote attacker can supply JavaScript input that triggers an exception and reaches jslPrintTokenLineMarker(), which passes the address of a 4-byte int column variable to jsvGetLineAndCol() as a size_t pointer. jsvGetLineAndCol() performs an 8-byte write through the mismatched pointer, overwriting adjacent stack memory.","state":0,"publishedAt":"2026-09-24T00:00:00+00:00","modifiedAt":"2026-09-25T15:14:38.255+00:00","affected":[{"ecosystem":"Vendor product","name":"n/a","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n/a\",\n                    \"product\": \"n/a\",\n                    \"versions\": [\n                        {\n                            \"version\": \"n/a\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/espruino/Espruino/commit/ecd7d43e084ba9aafa8245609347fe0f4383b38c"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-88388","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-88388","identifiers":["CVE-2026-88388"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
