How to prioritise Linux patching

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

  • 14 of 70 Linux CVEs (20%) are in CISA KEV: treat them as actively exploited and remediate them first, starting with CVE-2016-5195, CVE-2022-0847, CVE-2023-0386.
  • 1 CVE is known to be used in ransomware campaigns; patch these ahead of other KEV entries on internet-facing systems.
  • Outside KEV, the highest EPSS scores are CVE-2026-43500 (27%), CVE-2026-43284 (25.6%), CVE-2026-64530 (0.5%).
  • 1 CVE scores Critical and 28 High on CVSS v3 (maximum 9.8, average 7.7); sequence these after KEV and high-EPSS items.
  • 11 CVEs have a public exploit or proof of concept recorded, which shortens the time from disclosure to attack.

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.
