How to prioritise IBM patching

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

• No IBM CVE is in CISA KEV yet, so rank by exploit probability instead.
• Outside KEV, the highest EPSS scores are CVE-2026-81941 (0.8%), CVE-2026-82098 (0.8%), CVE-2026-81940 (0.5%).
• 6 CVEs score Critical and 17 High on CVSS v3 (maximum 9.9, average 7.4); sequence these after KEV and high-EPSS items.

About this data

Vendor attribution comes from the CNA and CPE product records of each CVE, folded to one vendor name; CVSS, EPSS and KEV status are read from the Threadlinqs CVE catalog; campaign and actor links come from tracked threat records. Counts reflect the data as of 2026-10-05 and refresh daily.
