What does Kubernetes 1.31 end of life mean?
When Kubernetes 1.31 reaches end of life, the maintainers stop issuing security patches for this version. CVEs discovered after the EOL date are publicly disclosed on the National Vulnerability Database with no patch available. Exploit code frequently appears on GitHub within days of disclosure.
The CVE blind spot: Most vulnerability scanners check for known CVEs but do not flag the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Running Kubernetes 1.31 past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.
Migrate to Kubernetes 1.36 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
Frequently Asked Questions
When does Kubernetes 1.31 reach end of life?
Kubernetes 1.31 reached end of life on October 28, 2025. This version is no longer receiving security patches.
Is Kubernetes 1.31 still supported?
No. Kubernetes 1.31 reached end of life on October 28, 2025 and is no longer receiving security patches.
What should I upgrade to from Kubernetes 1.31?
The recommended upgrade from Kubernetes 1.31 is
Kubernetes 1.36 — the latest actively supported version. Check the
Kubernetes full timeline for all supported versions.
What are the security risks of running Kubernetes 1.31 past EOL?
When Kubernetes 1.31 reaches end of life, the maintainers stop issuing security patches. Any CVEs disclosed after the EOL date accumulate with no remediation path. Most vulnerability scanners do not flag this — it is the CVE blind spot. Organizations running EOL Kubernetes should migrate immediately or implement compensating controls.
Does Kubernetes track end-of-life by point release (e.g. Kubernetes 1.36.1, Kubernetes 1.36.2)?
No — Kubernetes end-of-life dates apply to the entire 1.36.x release series, not individual point releases. A point release like Kubernetes 1.36.1 or Kubernetes 1.36.2 shares the same EOL date as Kubernetes 1.36. Security patches stop for the entire 1.36.x line on that date, regardless of which patch version you are running. Check the table above for EOL dates by major version series.
