Greg Kroah-Hartman, the maintainer responsible for the Linux kernel's stable branches, has released updates for three kernel versions simultaneously. The releases — 7.0.12, 6.18.35, and 6.12.93 — each contain important fixes throughout the tree, and users are advised to upgrade.
The releases were announced via LWN.net, which hosts the individual release notes for each branch.
Three Branches, One Message
The Linux kernel project maintains several stable branches in parallel, so that users on different release lines can continue to receive critical patches. The release announcements for all three branches carry the same advisory: update promptly.
The 7.0.12 release stands out for its major version number. The Linux kernel's major version has advanced incrementally over the years under Linus Torvalds's direction; the upstream announcement did not elaborate on any specific significance of the 7.0 milestone.
The 6.18.35 and 6.12.93 branches follow more conventional versioning patterns. The LWN announcement does not label any of the three branches as long-term support (LTS) releases.
What Administrators Should Do
Kroah-Hartman's guidance is straightforward: upgrade. Distribution vendors typically package stable kernel updates within days of their upstream release, so users of mainstream distributions such as Ubuntu, Fedora, and Debian can expect these fixes to arrive through their standard update channels shortly.
For organisations running custom-built kernels, the release is a prompt to review the relevant commit logs for the branch in use and assess whether any fixes address issues relevant to their workloads. Thorough testing in staging environments before broad rollout remains best practice.
負責 Linux kernel 穩定分支的維護者 Greg Kroah-Hartman 同時發佈了三個 kernel 版本的更新。這三個版本——7.0.12、6.18.35 及 6.12.93——均包含整個程式碼樹中的重要修復，建議用戶盡快升級。
相關發佈透過 LWN.net 公佈，該網站托管了各分支各自的發佈說明。
三個分支，同一訊息
Linux kernel 項目同時維護多個穩定分支，讓使用不同發佈線的用戶可持續獲得關鍵修補程式。三個分支的發佈公告均附帶相同建議：盡快更新。
7.0.12 版本因其主要版本號而引人注目。Linux kernel 的主要版本在 Linus Torvalds 的指導下多年來逐步遞增；上游公告並未具體說明 7.0 里程碑的任何特殊意義。
6.18.35 及 6.12.93 分支則遵循較為常見的版本編號模式。LWN 的公告並未將這三個分支中的任何一個標記為長期支援（LTS）版本。
管理員應採取的措施
Kroah-Hartman 給出的指引很直接：升級。發行版供應商通常會在上游發佈後數天內打包穩定 kernel 更新，因此 Ubuntu、Fedora 及 Debian 等主流發行版的用戶可預期通過其標準更新渠道很快獲得這些修復。
對於運行自訂 build kernel 的機構，此次發佈是一個提示，應審查正在使用的分支的相關提交日誌，並評估是否有任何修復解決了與其工作負載相關的問題。在廣泛部署前於預備環境中進行全面測試，仍然是最佳實踐。
