memory management

Windows is designed to make the most of every free megabyte of RAM — sometimes a little too aggressively — and a new wave of reporting linking a so-called “memory‑hungry” Windows feature to sluggish PCs has arrived at the same time scientists are reminding us that memory problems in people are...

Windows’ own update-sharing engine has quietly become the villain in a growing number of user reports: Delivery Optimization (DoSvc) — the peer‑to‑peer service that helps deliver Windows updates and Microsoft Store apps — can incrementally consume large amounts of RAM on some systems, producing...

Windows 11 can feel glossier than lean: that polish comes with a memory cost, but you don't have to accept a sluggish desktop or frequent paging as a fait accompli. This feature explains, verifies, and expands the practical steps that will actually reduce RAM usage in Windows 11 — from trimming...

Microsoft’s December cumulative update, KB5072033, fixed several visible quirks in Windows 11 but also introduced quieter service‑level changes that some users now blame for unexpectedly high RAM use — most notably reports that the Delivery Optimization service (DoSvc) and a reconfigured AppX...

The Linux kernel received a targeted correction that removes a surprising—and in some workloads, catastrophic—inefficiency in KSM scanning: scan_get_next_rmap_item now uses a range-walk helper to skip large unmapped holes instead of walking every address, fixing a case where ksmd could burn CPU...

A small, easily overlooked piece of memory-management logic in the HDF5 C library has been rewarded with a CVE and a fast upstream fix: CVE-2025-2925 identifies a double‑free in the HDF5 function H5MM_realloc (src/H5MM.c) that can be triggered when a caller passes an effective size of zero. The...

The HP OMEN 25L GT15 listing that’s circulating on marketplace pages promises a high‑end, turnkey gaming desktop built around a 14th‑Gen Intel Core i7 and NVIDIA’s mid‑range Blackwell GPU — but the headline specs and the listing source require careful verification before anyone types a credit...

Discord’s desktop client will quietly restart itself on Windows 11 when its RAM footprint climbs into multi‑gigabyte territory, part of a narrowly scoped experiment the company says is designed to reclaim memory, reduce system slowdowns, and buy engineering time to root out long‑running leaks...

Discord quietly confirmed a controversial experiment this week: its Windows desktop client will — under tight safeguards — automatically restart itself when memory use climbs above 4 GB as a stopgap while engineers hunt down persistent leaks and inefficiencies. Background Discord’s desktop...

Windows users are waking up to a simple — and costly — reality: many of the most popular desktop apps are now web apps in disguise, and that design choice is silently inflating RAM usage, causing sluggishness, shorter battery life, and harder choices about how much memory your next laptop needs...

Windows 11 users are suddenly facing a double squeeze: popular Chromium- and Electron-based apps — most notably Discord — are consuming far more RAM than many expect, and that problem is colliding with a memory market already strained by AI-driven demand and rising DRAM prices. What started as...

A small, surgical kernel change has been credited with closing a potentially disruptive hole in the Linux KVM stack: CVE-2024-43819 addresses a defect in the s390 KVM implementation that could lead to a null-pointer dereference when userland memory-region ioctls are used against ucontrol VMs...

The Linux kernel vulnerability tracked as CVE-2025-21696 — described upstream as “mm: clear uffd-wp PTE/PMD state on mremap” — is a correctness bug in the kernel’s memory-management paths that can produce kernel warnings, oopses, and denial-of-service conditions when specific userfaultfd and...

A subtle memory-management bug in the Linux kernel's StarFive crypto driver has been tracked as CVE-2024-39478 and fixed upstream — the flaw arises when code calls kfree on a variable-length buffer that was allocated on the stack, producing undefined behavior that can crash or destabilize...

The Linux kernel security community has assigned CVE-2025-37834 to a recently disclosed memory-management bug in mm/vmscan that can cause a kernel oops or panic by attempting to reclaim a hardware‑poisoned (hwpoison) folio; maintainers have published small, surgical fixes in upstream stable...

A subtle boot-time initialization bug in the Linux kernel has been disclosed and fixed under CVE-2025-40245: on nios2 systems using CONFIG_FLATMEM the kernel could miscalculate page-frame limits because memblock.current_limit was not pre-initialized before PFN limit calculations, potentially...

Valve’s Steam Machine is shaping up to be an intriguing living‑room PC, but recent tests show a clear and repeatable weakness: a GPU with only 8GB of dedicated VRAM can become a performance bottleneck — and, in current SteamOS betas, that bottleneck appears worse than the same hardware running...

Microsoft Edge’s appetite for RAM isn’t a mystery or a single bug — it’s the sum of modern browser design, heavy web pages, background extensions, and default behaviors — but the browser now gives you multiple, built‑in tools to diagnose, limit, and control that appetite, and using them together...

Microsoft’s Copilot Fall Release makes the assistant feel more social, more persistent, and — quite literally — more personable with a new animated avatar called Mico, expanded long‑term memory and connectors, collaborative Copilot Groups, and deeper agentic capabilities inside Microsoft Edge...

Anthropic has rolled out an optional Memory capability for Claude that is now available to Team and Enterprise plan customers, enabling the assistant to retain and recall project- and work-related context across sessions while giving admins and users controls to view, edit, and disable what the...
