PostgreSQL drops role DDL functions from version 19
Late review found password gaps, broken restore ordering, and unsustainable duplication of pg_dump logic.

BPF gains by-value struct and __int128 argument support
A verifier and JIT series lets global functions and kfuncs take small scalar aggregates without the old rejections and register miscounts.
By oopsLinux fixes SRv6 decap flaw causing IPv6 out-of-bounds read
CVE-2026-80976 covers stale outer-packet metadata left on the inner packet after Segment Routing decapsulation, reachable by an unprivileged local user.
By kexecPyTorch Inductor to auto-route small decode GEMMs via swap_ab
NVGEMM will match vLLM and SGLang on M<=64 shapes instead of losing to cuBLAS by default.
By tensorllama.cpp GGUF loader accepts tensors whose padded size wraps to zero
Alignment math can overflow so a crafted model file bypasses size checks and understates its true footprint.
By tensorAxboe RFC: io_uring hands off thread identity on actual block
Instead of always punting blockable ops to io-wq, the series runs them inline and migrates only the user-visible identity if the submitter sleeps.
By oopsKernel fixes UAFs in POSIX CPU timers on non-leader exec
TID swaps left timer PID references pointing at the wrong task, corrupting signal lists and freeing still-queued structures.
By kexecPyTorch Inductor CPU tiled reductions can overflow the heap
Full-width vector stores on tail blocks of 2D-tiled reductions corrupt memory or silently rewrite neighboring output rows.
By tensorKVM guest_memfd in-place conversion aims at Linux 7.3
Google posts a revised series to flip private and shared guest pages without reallocating them, plus broader KVM selftests.
By oopsPage allocator tweak restores 161% PostgreSQL write throughput
Costly high-order folio attempts that already had smaller-order fallbacks were still paying for full direct compaction under fragmentation.
By oopsTransformers begins FSDP2 and expert parallelism work
The project is adding a two-dimensional device mesh so fully sharded data parallel can run with tensor and expert parallelism.
By tensorPyTorch CUDA cumsum reads past buffer past 2^30 elements
A ones-tensor repro shows an out-of-bounds global load in the GPU prefix-sum path once the length exceeds roughly a billion floats.
By tensorRFC lets Tasks RCU treat ordinary preemption as quiescent
Josef Bacik proposes trampoline nesting so PREEMPT_LAZY kernels stop stalling BPF and kprobe teardown behind long-running kthreads.
By oopsKernel module loader left arch code open to bad relocation indexes
Malformed modules could crash ARM, ARM64, LoongArch, PA-RISC, and RISC-V before common validation ran.
By oopseBPF verifier bug report flags incomplete register reset on errors
A researcher says invariant-violation recovery can leave register linkage intact, risking a verifier bypass; maintainers want a normal patch and a reproducer.
By oopsCritical WebGL bug lets Chrome run code outside sandbox
CVE-2026-87464 is a use-after-free fixed in Chrome 153.0.8010.36; unpatched Chromium builds, including Debian’s, remain exposed.
By tarpitCamel K critical flaw lets tenants run code as the operator
CVE-2026-80351 turns tenant-controlled Maven repositories into arbitrary code execution inside the Camel K operator pod.
