From standards text and theorem provers to kernel selftests and release cadence, open source is arguing over what machine authorship changes about responsibility.
By ttlLinux swap faults stop spinning forever on bad entries
A Meta engineer’s patches rate-limit the log spam and turn permanent swap PTE corruption into SIGBUS instead of an infinite retry.

Nine patches harden hp-bioscfg against out-of-bounds memory access and broken ACPI attribute parsing on HP machines.

Missing file_operations ownership in Rust DRM and misc helpers let the kernel call into unloaded code after rmmod.
By renderLinux proxy execution gains optional sched_ext BPF support
Andrea Righi's series ends a build-time mutual exclusion so one kernel can ship both features and let BPF schedulers opt in at runtime.
By kexecLinux makes per-VMA locks unconditional across all configs
A Hansen/Baghdasaryan series drops architecture guards so binder and TCP paths can stop falling back to mmap_lock.

A config rename left the CVE-2026-68480 fix inert on the long-term 6.6 series until corrected patches land.
By oopsBPF gains 16-byte aggregate returns via R0:R2 pair
Kernel verifier and JITs learn LLVM 23's convention so subprograms and kfuncs can return __int128 and small structs by value.
By oopsLinus rejects per-CPU page tables as general MM design
ARM64 this_cpu_* optimization RFC hits a hard architectural wall over divergent kernel page tables.
By oopsKernel fix corrects wrong TLB flush in page table reclaim
Direct reclaim after MADV_DONTNEED could free a page table while leaving a stale paging-structure cache entry.

Omitted commits from a 2024 pipapo series leave use-after-free and double-free bugs in 6.6.y and older trees.
By kexecBPF stack helpers race fixed to stop out-of-bounds writes
Preemptible programs could reuse a per-CPU callchain buffer and inflate the copy length past the caller's buffer.

Greg Kroah-Hartman says automated cleanups defeat the subsystem's role as a training ground for new developers.
