{"id":"CVE-2026-35001","summary":"OpenS100 S-102 Parser Integer Overflow Heap Buffer Overflow","details":"OpenS100 through commit daa35b contains an integer overflow vulnerability in the S-102 Bathymetric Surface parser that allows remote attackers to cause a heap-based buffer overflow by opening a crafted S-102 HDF5 file with malicious grid dimension metadata. Attackers can exploit the unvalidated multiplication of numPointsLatitudinal and numPointsLongitudinal values in the S102_VG_BathymetryCoverage::Read() function to trigger a 32-bit integer wraparound, resulting in undersized heap buffer allocation and subsequent out-of-bounds writes that lead to application crash or arbitrary code execution.","modified":"2026-10-14T02:48:28.807436680Z","published":"2026-10-13T01:39:03.514Z","database_specific":{"cwe_ids":["CWE-122","CWE-190"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35001.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35001.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35001"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/opens100-s-102-parser-integer-overflow-heap-buffer-overflow"},{"type":"PACKAGE","url":"https://github.com/S-100ExpertTeam/OpenS100"},{"type":"EVIDENCE","url":"https://doi.org/10.3390/s26206448"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/S-100ExpertTeam/OpenS100","events":[{"introduced":"0"},{"last_affected":"daaa35b19b789aa4b170bdcc300763a287d73164"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-35001.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
