Debian 11 End of Life Date
Debian 11 end-of-life date, support status, and CVE risk. Data reconciled from official vendor documentation and endoflife.date at every build; the source of each date is on the product page.
⚠
Debian 11 is past its standard end-of-life date, but still receiving security patches. Debian LTS covers this version until June 30, 2031 at no cost. Plan your migration for that date — after it, no patches of any kind.

Lifecycle detail
Debian 11 was released on August 14, 2021 and support ended on August 31, 2026 — a supported lifespan of 5 years and 1 month, longer than the 4 years median for Debian releases. Its most recent release is 11.11, published August 31, 2024. Standard support ended 23 days ago. Security fixes now come only through extended support, published to June 30, 2031; without it this version is unpatched.

What does Debian 11 end of life mean?
When Debian 11 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: A CVE-based scan does not show the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Some scanners flag unsupported versions of common products, but coverage varies, and none of them give you the date in advance. Running Debian 11 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to Debian 13 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
Frequently Asked Questions
When does Debian 11 reach end of life?
Debian 11 reached end of life on August 31, 2026. This version is no longer receiving security patches.
Is Debian 11 still supported?
No. Debian 11 reached end of life on August 31, 2026 and is no longer receiving security patches.
What should I upgrade to from Debian 11?
The recommended upgrade from Debian 11 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 11 past EOL?
When Debian 11 reaches end of life, the maintainers stop issuing security patches. Any CVEs disclosed after the EOL date accumulate with no vendor fix. A CVE-based scan does not show this — it is the CVE blind spot; some scanners flag unsupported versions of common products, but coverage varies and none give the date in advance. 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.
