Virtual swap collides with what memory.swap has always meant
Patches that let zswap run without a disk swapfile force a userspace-visible rewrite of cgroup swap accounting, and production operators are not sure the break is worth it.

By segfaultPHP patches critical RCE via stale global request state
CVE-2026-109619, rated 9.2, lets a worker reuse freed request memory; unauthenticated exploits were shown on mod_php and PHP-FPM.
By tarpitPostgreSQL moves toward custom storage options for table access methods
A long-running patch would let non-heap table AMs own their WITH/SET parameters instead of inheriting heap’s, with dump and locking rough edges still under review.

Updated ca-certificates package blocks a dozen certificates whose private keys were the integers 4, 56, and 115.

FileSystemReader could map local .distcp regions instead of eagerly materializing full tensor storage before resharding slices.
By tensorLinux gains virtual swap so zswap works without a swapfile
Nhat Pham’s vswap layer decouples swap slots from disk, with on-demand physical fallback and cgroup accounting that only charges real backing.

Sasha Levin’s series gives coding assistants shared recipes for wrong Fixes tags, stable eligibility, sibling bugs, and commit messages.
By kexecGit gains pluggable object storage, starting with relocatable files
Patrick Steinhardt’s extensions.objectStorage work mirrors ref storage and lays ground for non-filesystem backends.

A 22-patch series moves amdgpu unified memory onto the same HMM page-migration stack Xe already uses, starting with single-GPU XNACK-on.
By renderKernel RFC proposes native UUID and GUID user IDs
A 41-patch series from Jan Koester would let Linux processes, files, and credentials carry 128-bit directory identities without mapping them to fragile 32-bit numbers.

Forward-only 4-bit support forces a costly upcast, blocking native low-precision fine-tuning on modern NVIDIA GPUs.

Eduard Zingerman’s scalar-evolution work cuts verification cost sharply, but 32-bit pointer latches can undercount iterations and mis-bound memory access.
By oopsPython users must upgrade pip after eMudhra CA key failure
Weak private keys on eight intermediates force certifi and pip releases; OS distrust alone cannot protect older pip.
By segfaultKernel tool will stop CCing LKML on nearly every patch
get_maintainer will treat linux-kernel as a fallback only, aiming to cut the list’s duplicate traffic by roughly 90 percent.
