CVE-2026-8358
Detail
Not Scheduled
This CVE record is not being prioritized for NVD enrichment efforts due to resource or other concerns.
Description
LibreOffice Calc can import tracked changes from a spreadsheet document. A heap buffer overflow existed when a document reused the same change identifier for two different kinds of change. The importer then treated one change object as a different, larger type and wrote past the end of its allocation. In fixed versions records with a duplicate identifier are rejected.
