Description

CVE-2026-97222 is a medium severity heap use-after-free vulnerability in GNOME Gnumeric. It is triggered when a user opens a specially crafted workbook containing a malformed SheetObjectComponent element, causing the XML parser to dereference a freed sheet-object component and crash the application. This affects Gnumeric versions 1.11.0 and later. The vulnerability has a CVSS score of 5.5 and does not impact confidentiality or integrity but causes availability disruption due to application crashes.
