LineageOS 17.1 End of Life Date
LineageOS 17.1 end-of-life date, support status, and CVE risk. Data from endoflife.date and official vendor documentation.
LineageOS 17.1 was released on February 1, 2020 and support ended on April 26, 2022 — a supported lifespan of 2 years and 3 months, in line with the 2 years median for LineageOS releases. It has been without security patches for 4 years and 4 months. 6 newer LineageOS releases have shipped since.
What does LineageOS 17.1 end of life mean?
When LineageOS 17.1 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 LineageOS 17.1 past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.
Migrate to LineageOS 23.2 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
