The public preview of Amazon Linux 2027 arrived on September 3 with a 7.1 kernel, SELinux enforcing by default, and AWS Neuron driver support. Test it now if you are planning an AL2023 migration.
On August 29, 2026, Konstantin Ryabitsev published hard numbers on AI crawler traffic to the Linux kernel repositories: six million requests a day, a fifth of CPU capacity, and barely 2% legitimate traffic. For any public self-hosted service, it is proof that a proof-of-work challenge only moves the problem.
On August 25, 2026, Cong Wang released mklinux v7.0-mk2, the first ready-to-run build of the multi-kernel concept: several independent Linux kernels on one physical machine, with no hypervisor and no emulation. A promising path to hard isolation — but not yet a production artifact.
The Linux kernel’s NTFS3 driver restores setuid bits straight from untrusted on-disk data, letting a crafted NTFS image produce a setuid-root binary as soon as the volume mounts. Reported privately two months ago and still unpatched, the bug hits desktops whose automounter mounts NTFS volumes with suid on by default.
Kaspersky has found a new CoolClient backdoor variant carrying a signed kernel driver that hides processes, files, registry keys, and network connections. The HoneyMyte group (Mustang Panda) is using it against governments in Asia — detecting it requires kernel-level telemetry.
The Linux project published 46 CVEs between August 2 and 8, 2026. Every single one is already fixed in stable, none are 0-days, but the gap between the available patch and the kernel running on your machines is the real risk.
On August 6, 2026, the Linux WiFi maintainer announced a three-second rejection rule for AI-generated patches, as the networking subsystem continues to be flooded with automated contributions. Open-source network infrastructure maintainers are raising the alarm: code quality is at risk.
On August 6, 2026, a speculative execution vulnerability was publicly disclosed, affecting all AMD Zen 1 through Zen 4 processors via the Linux kernel's SRSO mitigation. A fix is already in linux.git; the community must patch without delay.
A freshly provisioned Ubuntu VPS on Hetzner, OVH, or DigitalOcean receives its first SSH brute-force attempt within 12 minutes. These 10 commands — AppArmor, firewalld, fail2ban, auditd, AIDE, kernel hardening, Lynis, and unattended-upgrades — lock it down in 5 minutes flat.
