The public needs to be aware

Roman Gushchin began his session in the memory-management track of the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit by saying that the community has seen a lot of proposals adding BPF-based interfaces for memory management. None of them have made their way into the mainline, though. He wanted to explore the ways in which BPF might be helpful and the obstacles that have kept BPF-based solutions out so far. This session was followed by a discussion led by Shakeel Butt on what the requirements for a new, BPF-based interface for memory control groups might look like.

Greg Kroah-Hartman has announced the 7.0.8, 6.18.31, 6.12.89, 6.6.139, 6.1.173, 5.15.207, and 5.10.256 stable kernels. These kernels contain a patch for CVE-2026-46333 a vulnerability reported by the Qualys Security Advisory team, though Jann Horn proposed a patch in 2020. The vulnerability has a proof-of-concept exploit published already. Some of the kernels have additional patches for other bugs; as always, users are advised to upgrade.

Recent times have seen a lot of effort put into the implementation of the kexec handover and live update orchestrator features in the Linux kernel. But that work is not yet complete. At the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, Pratyush Yadav led a memory-management-track session on adding the ability to preserve hugetlbfs-provided memory during the live-update process.

Earlier this year we reviewed the ZimaBoard 2 for building a Linux home storage server. That was a nifty little device but for those looking for a more polished product than assembling your storage devices in cardboard cut-outs and the like, IceWhale has launched the ZimaCube 2. The ZimaCube 2 is a nice and polished, literal cube, to serve as your personal cloud / network attached storage (NAS) device.
