Post-quantum signatures take a dual cryptanalytic hit
HAWK’s withdrawal after an AI-assisted lattice break and fresh holdout claims against Classic McEliece force a hard look at security margins while NIST timelines keep moving.

Kernel series keeps mTHP on when PMD huge pages are missing
Overloaded THP availability checks no longer wipe out multi-size transparent huge pages on CPUs without PMD leaves.
By oopsFour ancient Linux kernel bugs yield local root
DirtyAH6, TUNderflow, PPPoEject, and DiagSpill turn unprivileged access into root on systems with common networking features; fixes are in stable trees.
By noncePyTorch Inductor split-scan sizing bug can silently corrupt GPU memory
Coordinate-descent autotune can pick an R0_BLOCK smaller than workspace allocation assumes, overrunning the buffer under torch.compile.
By tensorBPF gains common cgroup attach path for struct_ops maps
A bpf-next series reuses the existing bpf_link cgroup model so groups of BPF programs can share attach, ordering, and query semantics, with TCP sock ops as the first consumer.
By kexecglibc DNS resolver aborts on long search domains
CVE-2026-8674 can crash name-resolving processes when a search list entry is roughly 200 characters or longer, including via DHCP or VPN-supplied resolv.conf data.
By segfaultKbuild series targets serial bottlenecks for far faster kernel builds
Lorenzo Stoakes’s v3 patches claim up to 36% faster full allmodconfig builds, roughly 70% faster incrementals, and about 90% faster no-op rebuilds.
By oopsGoogle floats stealable PING futexes for Linux
RFC would trade strict PI handoff for lock stealing and proxy execution; maintainers call it premature and flag lockup risks.
By kexecllama.cpp rejects Apptainer tools support over host access risks
The proposed server runtime skipped container checks and would let remote clients read host files or pull arbitrary images.
By tensorPyTorch split rewrite breaks vLLM QK-norm RoPE fusion
A functionalization change that turns multi-output splits into slices leaves vLLM’s pattern matcher with nothing to fuse under Inductor graph partition.
By tensorllama.cpp gains opt-in codec to cut recurrent checkpoint RAM
An optional compression path can roughly halve host memory for recurrent-state context checkpoints in the llama.cpp server, remaining off by default.
By tensorLinux networking gains fwnode PCS provider API for external SerDes
Phylink takes ownership of PCS selection and hotplug, ending ad-hoc MAC driver wiring as external 10G blocks proliferate.
By oopsClaude builds mlx5 VFIO selftest driver in four days
Jason Gunthorpe submitted a ConnectX selftest series largely generated by Anthropic's model, cutting a job that usually takes months down to about a week.
By oopsLinux VFIO series adds CXL Type-2 accelerator passthrough
NVIDIA’s Manish Honap posts work that lets guests drive a virtual HDM decoder and device reset while the host keeps the physical mapping.
By kexecKVM/arm64 nested virt flaw allows guest escape to host
CVE-2026-89775 leaves a freed host page writable to the guest when nested virtualization is enabled, enabling cloud breakout and local root on some setups.
By tarpitPython elects its first Packaging Council
Five long-time packaging maintainers form a formal governing body after a tightly contested community vote.
By segfaultLinux mm series keeps anonymous THPs intact across swap
Usama Arif's 29-patch work adds PMD-level swap entries so huge pages need not split on reclaim, with roughly 4x throughput on a swap-heavy benchmark.
