How to prioritise Hewlett Packard Enterprise (HPE) patching

This order follows the data Threadlinqs holds for Hewlett Packard Enterprise (HPE), not a generic severity checklist:

• No Hewlett Packard Enterprise (HPE) CVE is in CISA KEV yet, so rank by exploit probability instead.
• Outside KEV, the highest EPSS scores are CVE-2026-23816 (1.2%), CVE-2026-23815 (1%), CVE-2026-73749 (0.8%).
• 2 CVEs score Critical and 13 High on CVSS v3 (maximum 9.8, average 8.4); sequence these after KEV and high-EPSS items.
• 5 CVEs have a public exploit or proof of concept recorded, which shortens the time from disclosure to attack.
