Linux Kernel: Hardening Push and Scheduler Reliability Fixes

The cycle is dominated by hardening and correctness fixes across filesystems, networking, and BPF, plus reliability work for extensible scheduling and cgroups. RISC-V, Hyper-V, and Rust bring smaller performance and tooling updates.

Good morning, it's Friday, October 30th, 2026, and this is your Linux Kernel briefing.

The lead pattern is defensive fixes over features, with corrupted input and fallback paths getting most of the attention.

First, hardening against bad data. The N-T-F-S-three update, merge zero-ff-eight-f-forty, is largely fuzzing and kernel address sanitizer reports. Unchecked log replay sizes could write past the master file table buffer, a bad extended attribute could leak up to sixty-four kilobytes of kernel heap through get…

Second, keeping tasks and containers under control. The extensible scheduler fixes, commit seven-two-nine-beb-five, address sub-schedulers that nest under a parent. Fallback paths meant to keep tasks moving could leave them stuck, the stall watchdog could blame the wrong scheduler, and sub-schedulers learned late…

Finally, platform and tooling polish. The RISC-V pull adds crash hotplug, faster user copies on cores with fast misaligned access, cheaper page-table level checks, and bounds checks on shadow stack restore. Hyper-V hardens the V-M-Bus ring indices and reworks memory deposit logic. Rust fixes control-flow integrity…

What's next: test mounts of untrusted N-T-F-S…
