Hello, it's September 25th, 2026, and this is your Linux Kernel briefing.

The lead pattern is late-cycle hardening, with a 189-commit networking pull at the center, backed by scheduler and security tracing corrections aimed at crashes, stalls, and bad telemetry.

First, networking reliability. The merge in commit f2c53ea covers drivers, core protocols, and packet handling, with maintainers noting no new regressions. Supporting commits show the shape of the risk. Virtual LAN header handling now ensures sufficient headroom for packets built before device changes, preventing a…

Second, extensible scheduler correctness, in commit ee9c669. A task requeued during dispatch could lose all future dispatches. A remote wakeup could strand a local requeue request that, if the scheduler unloaded, pointed at freed memory. The dequeue callback ran with a queue lock held, risking deadlock if schedulers…

Third, Landlock security tracing, in commit 415f204. Denial and rule events now report the intended policy context for filesystem, network, and process controls, with updated tests and docs, so audit tools see accurate blockers.

Also noted: a cgroup process-number event notification fix, and a…
