Alpine Linux has released simultaneous security updates for its four supported branches: 3.21.8, 3.22.6, 3.23.6, and 3.24.2, primarily addressing OpenSSL vulnerabilities. The newer branches have upgraded to OpenSSL 3.5.8, while the older 3.21 branch remains on 3.3.7, reflecting Alpine's backporting approach as the branch approaches its end of support on November 1, 2026. Operators are advised to plan migrations from the 3.21 branch, as it will not receive any further updates after the support deadline. Additionally, the updates include various other security and bug fixes, and users upgrading to a major version should follow specific commands for a successful transition

Alpine Linux released simultaneous security updates across all four of its supported branches: 3.21.8, 3.22.6, 3.23.6, and 3.24.2. The three newest branches jumped to OpenSSL 3.5.8 while the older 3.21 line stayed on 3.3.7, a divergence that reflects Alpine's backporting approach as branches near end of support. For 3.21 in particular, this is one of the final security patches, since the branch loses support on November 1, 2026, giving operators about six weeks to plan a migration. Those upgrading a major version should run apk upgrade --available and re-run grub-install afterward if they use GRUB.
