## How to prioritise TeamViewer patching

This order follows the data Threadlinqs holds for TeamViewer, not a generic severity checklist:

- No TeamViewer CVE is in CISA KEV yet, so rank by exploit probability instead.
- Outside KEV, the highest EPSS scores are [CVE-2025-0065](https://intel.threadlinqs.com/cve/CVE-2025-0065) (0.6%), [CVE-2026-92370](https://intel.threadlinqs.com/cve/CVE-2026-92370) (0.4%), [CVE-2025-36537](https://intel.threadlinqs.com/cve/CVE-2025-36537) (0.2%).
- 0 CVEs score Critical and 7 High on CVSS v3 (maximum 8.8, average 7.6); sequence these after KEV and high-EPSS items.
