## How to prioritise Wireshark Foundation patching

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

- No Wireshark Foundation CVE is in CISA KEV yet, so rank by exploit probability instead.
- Outside KEV, the highest EPSS scores are [CVE-2026-76928](https://intel.threadlinqs.com/cve/CVE-2026-76928) (0.3%), [CVE-2026-76919](https://intel.threadlinqs.com/cve/CVE-2026-76919) (0.2%), [CVE-2026-76926](https://intel.threadlinqs.com/cve/CVE-2026-76926) (0.2%).
- 0 CVEs score Critical and 1 High on CVSS v3 (maximum 7.5, average 4.9); sequence these after KEV and high-EPSS items.
