BPF stack limit proposed to rise from 512 bytes to 2 KiB
x86-64 and arm64 JITs would get the larger budget; the interpreter and other architectures stay at 512 bytes.
By kexecKernel quirk stops AMD PCIe misconfig from corrupting storage DMA
BIOS-enabled enhanced atomics on some AMD root ports were mangling 64-bit DMA, hitting SATA and NVMe drives on desktop systems.

CVE-2026-93834 addressed a worker-thread path mutation that main-thread readers did not lock against.
By sudoHMM migrate-on-fault series aims to cut page-table walks
A fourteenth revision unifies fault handling with device-page migration, but automated review flagged livelocks, notifier imbalances, and missing TLB flushes.
By renderBPF exception unwinds gain cleanup pads for Rust Drop
Yonghong Song’s bpf-next series makes bpf_throw() run compiler-emitted landing pads so resource-owning frames can release locks and values on the way out.

Last Call on the IETF applicability statement reopenes a fight over whether receivers must be able to take mail without TLS.
By ttlsched_ext and proxy execution set to share one Linux kernel
