Greg Kroah-Hartman has released stable Linux kernel updates for versions 6.12.104, 6.18.45, and 7.1.9, each containing between 180 to 272 maintenance patches that focus on networking stability, Thunderbolt peripheral validation, and BPF reference counting races. The updates include significant improvements, particularly in the 7.1.9 build, which enhances scheduler performance and USB 3.0 host controller management, while also extending support for longterm branches until December 2028. The patches address critical vulnerabilities such as use-after-free and out-of-bounds access issues, with specific fixes aimed at hardware attack surfaces like Thunderbolt devices. Distro maintainers are expected to implement these updates soon, making it essential for administrators to prioritize their application to enhance security

Greg Kroah-Hartman released three more stable Linux kernel updates targeting the 6.12, 6.18, and 7.1 branches. Each release brings roughly 180 to 272 maintenance patches focused heavily on networking stability, BPF reference counting races, and Thunderbolt peripheral validation. The 7.1.9 build notably advances scheduler improvements and USB 3.0 host controller handling, while the longterm branches continue extending their support windows toward December 2028. Distro maintainers are expected to roll these fixes out within days, so administrators should prioritize applying the updates to close active use-after-free and out-of-bounds vulnerabilities.
