Red Hat has confirmed that Fedora Linux version 42 has reached its end of life. The operating system will no longer receive any further updates or security patches as of May 28, 2025. Users running this specific release must take action to maintain a secure computing environment.
Red Hat confirms security updates have stopped for the release, urging administrators to migrate systems immediately.
Fedora serves as a testing ground where new features are developed before being integrated into Red Hat Enterprise Linux. Version 43 currently serves as the active supported release for users who need ongoing maintenance and security fixes. Fedora follows a structured release schedule that provides users with defined periods of security updates for each version.
The Fedora 42 release cycle concluded without any further software updates being issued by the development team. System administrators should verify their current operating version immediately to identify if they are still running the unsupported build. Transitioning to a supported release prevents exposure to unpatched vulnerabilities.
Fedora 43 provides full support until one month after the release of Fedora 45. The longer support period for Fedora 43 gives users sufficient time to prepare for future transitions while keeping systems secure. Fedora provides straightforward guidance to help users move to supported versions and keep their computers running securely.
Users should initiate an immediate upgrade to Fedora 43 to restore full security coverage. Postponing the upgrade leaves systems vulnerable because they will no longer receive security fixes after Fedora 42 reaches end of life. The Fedora project advises users to switch to a supported version immediately to maintain system safety.
