An attacker can supply a crafted S-102 HDF5 file with malicious grid dimension metadata that causes memory corruption when a user opens it. In the S102_VG_BathymetryCoverage::Read() function, the numPointsLatitudinal and numPointsLongitudinal values are multiplied without validation, and the 32-bit result can wrap around, producing an undersized heap buffer allocation. Subsequent writes past the end of that buffer cause a heap-based buffer overflow, leading to an application crash or potential arbitrary code execution in the context of the user who opened the file.","state":0,"publishedAt":"2026-10-13T01:39:03.514+00:00","modifiedAt":"2026-10-15T14:56:56.412+00:00","affected":[{"ecosystem":"Vendor product","name":"OpenS100","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"OpenS100 Project\",\n                    \"product\": \"OpenS100\",\n                    \"repo\": \"https://github.com/S-100ExpertTeam/OpenS100\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"2b1dafc11332a0a68930c687bde57b2e41074342\",\n                            \"versionType\": \"git\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7,"severity":"HIGH"}],"references":["https://doi.org/10.3390/s26206448","https://www.vulncheck.com/advisories/opens100-s-102-parser-integer-overflow-heap-buffer-overflow"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-35001","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-35001","identifiers":["CVE-2026-35001"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
