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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":51,"depthScoreParts":{"impact":38.5,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":222399,"id":"CVE-2026-35001","ts":1792077080423,"field":"exploit_available","old":"false","new":"true"},{"seq":220314,"id":"CVE-2026-35001","ts":1791996105939,"field":"cvss","old":"7.8","new":"7"}]}
