What does Debian 9 end of life mean?
When Debian 9 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 Debian 9 past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.
Migrate to Debian 13 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
Frequently Asked Questions
When does Debian 9 reach end of life?
Debian 9 reached end of life on July 18, 2020. This version is no longer receiving security patches.
Is Debian 9 still supported?
No. Debian 9 reached end of life on July 18, 2020 and is no longer receiving security patches.
What should I upgrade to from Debian 9?
The recommended upgrade from Debian 9 is
Debian 13 — the latest actively supported version. Check the
Debian full timeline for all supported versions.
What are the security risks of running Debian 9 past EOL?
When Debian 9 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 Debian should migrate immediately or implement compensating controls.
Does Debian track end-of-life by point release (e.g. Debian 13.1, Debian 13.2)?
No — Debian end-of-life dates apply to the entire 13.x release series, not individual point releases. A point release like Debian 13.1 or Debian 13.2 shares the same EOL date as Debian 13. Security patches stop for the entire 13.x line on that date, regardless of which patch version you are running. Check the table above for EOL dates by major version series.
