The latest round of open-source AMD driver work and kernel/toolchain updates are materially improving Llama.cpp AI inference performance on Linux — in some cases outpacing equivalent Windows 11 setups — thanks to targeted RADV/Mesa optimizations, newer Linux kernels, and the way Vulkan-based...

For a surprising number of Windows systems, the guilty party behind intermittent stutters, dropped frames, and mysteriously sluggish behaviour isn’t a CPU pegged at 100% or a full SSD — it’s the tiny, sub-millisecond interruptions inside the kernel that LatencyMon can expose and quantify in...

A routine security update intended to tighten Windows kernel defenses has instead opened a new attack vector: a reliably exploitable information‑disclosure bug tracked as CVE‑2025‑53136 that leaks kernel addresses on Windows 11 and Windows Server 2022 24H2 builds. The vulnerability—rooted in...

Microsoft’s latest Canary-channel flight, Windows 11 Insider Preview Build 27943, is a compact but consequential maintenance update that repairs a handful of user-facing regressions — most notably a stuck Temporary files scan in Settings and an HDR toggle that would mysteriously disable itself —...

Oracle’s VirtualBox 7.2.2 arrives as a focused maintenance release that patches several painful regressions introduced with the 7.2 series—most notably virtual machines failing to start on Windows‑on‑ARM hosts, Trusted Platform Module (TPM) emulation problems for some guests, multiple GUI...

Microsoft’s advisory for CVE-2025-55224 describes a concurrency flaw in the Windows kernel graphics component (Win32K — GRFX) that can be manipulated by an authorized local actor to gain code execution or elevate privileges on an affected system; the bug is a race condition (improper...

Microsoft’s Security Response Guide lists CVE-2025-54112 as a vulnerability in the Microsoft Virtual Hard Disk (VHD/VHDX) handling code that can be abused by an authorized local attacker to achieve elevation of privilege on Windows hosts, a condition vendors and incident responders classify as...

Title: CVE‑2025‑54093 — Windows TCP/IP Driver TOCTOU Race Condition (Local Elevation of Privilege) Summary What it is: A time‑of‑check/time‑of‑use (TOCTOU) race condition in the Windows TCP/IP driver that Microsoft lists as CVE‑2025‑54093. Microsoft’s advisory describes the flaw as a TOCTOU...

Microsoft’s advisory identifies CVE-2025-53803 as a Windows Kernel memory information disclosure vulnerability: an error message generated by kernel code can contain sensitive kernel memory contents, allowing an authenticated local actor to read data that should remain protected. Background The...

Microsoft’s advisory listing for a DirectX Graphics Kernel race-condition that could permit local elevation of privilege — referenced by the CVE identifier the user provided (CVE-2025-55223) — cannot be located in Microsoft’s public Security Update Guide pages that are accessible without...

A newly reported Windows NTFS vulnerability described as a stack-based buffer overflow that “allows an authorized attacker to execute code locally” has raised immediate concern—but the specific CVE identifier you provided (CVE-2025-54916) could not be located in public vendor and vulnerability...

xAI’s decision to plant an engineering flag in Seattle this week marks a consequential expansion for Elon Musk’s fast-moving AI startup—one that arrives at the intersection of talent, cloud partnerships, and high-profile litigation that together will shape how Grok and xAI compete in the...

Microsoft has quietly opened the gates: Windows 11 version 25H2 is now available to testers in the Windows Insider Release Preview channel as a small, fast enablement package that flips features already staged in the 24H2 servicing branch — which means you can install the 2025 annual update on...

Microsoft's effort to let device-driver developers use Rust has moved from research and experiments into tangible tooling and samples, but the path to production-ready Windows drivers written in Rust remains long and cautious — working prototypes and Microsoft-backed crates exist, CodeQL now...

WAVLINK’s entry-level 10GBase‑T PCIe card — sold under model WL‑NWP004 and branded across marketplaces as a “WAVLINK 10G Base‑T PCIe Network Card” using an AQC113 controller — promises a low‑cost gateway to 10Gbps Ethernet for desktop builders, but a closer look at the hardware, drivers and the...

Windows Subsystem for Linux has quietly become one of the most consequential developer features in Windows 11 — not because it’s flashy, but because it removes long-standing friction between two operating systems that many of us need to use every day. What used to require dual‑booting, slow...

The GNU Linux-libre 6.16 release lands on August 24, 2025 with a familiar promise and a precise mandate: take everything new and noteworthy in upstream Linux 6.16 and remove the parts that depend on proprietary firmware, binary-only microcode, or unclear redistribution terms, then ship a kernel...

Siemens’ advisory covering third‑party components in SINEC OS landed as a stark reminder that industrial network stacks are only as strong as their weakest third‑party link: dozens of kernel and userland weaknesses, CVEs spanning classic buffer overflows to TOCTOU races, and a vendor‑centric...

Microsoft has released patches for a kernel-mode flaw in the Kernel Streaming WOW Thunk Service Driver—an exploitable heap-based buffer overflow that can allow a locally authorized attacker to escalate privileges to SYSTEM—though the CVE identifier you supplied (CVE-2025-53149) does not appear...

Below is a comprehensive technical brief on CVE-2025-53135 (DirectX Graphics Kernel — elevation of privilege via a race condition). I searched Microsoft’s Security Update Guide and the public vulnerability databases for corroborating information; where vendor-provided details are available I...
