CVE-2026-97767 is a remote code execution flaw in Microsoft Office Excel, rated High Severity (CVSS 8.8), that affects the volume-licensed LTSC builds: Office LTSC 2021 in both 32-bit and 64-bit editions and Office LTSC 2024 for 64-bit. LTSC installs are common in regulated, kiosk, and air-gapped style environments where patching often lags the Microsoft 365 Apps channels, so exposure may last longer there. There is no sign of active exploitation yet (not in CISA KEV, no known ransomware use, EPSS at 1%), which makes this a good window to patch ahead of any public exploit.
Do this: Inventory machines running Office LTSC 2021 and 2024, then deploy the Microsoft security update for this CVE to them this patch cycle, starting with systems where users routinely open Excel files from email or external sources.
