CVE-2025-10999Public exploit

Local crash via unchecked internal-coordinate pointer

Published Sep 26, 2025 · Updated Sep 26, 2025

NULL pointer dereference in Open Babel 3.1.1 and earlier allows local users to crash processing via a crafted CACAO file. CacaoFormat::SetHilderbrandt assumes every OBAtom pointer in its internal-coordinate list is valid and calls OBAtom::GetIdx on a null entry. The crash requires processing the malicious file through obabel, the OBConversion API, or a language binding; no data disclosure or modification is reported.
