Microsoft fixes six actively exploited flaws in latest Windows 11 update

Microsoft's February 2026 Patch Tuesday addressed 59 vulnerabilities in Windows 11, with six confirmed as actively exploited. The most critical vulnerability is CVE-2026-21510, a Windows Shell security feature bypass with a CVSS rating of 8.8, allowing attackers to evade warnings by tricking users into opening malicious files. Another significant vulnerability, CVE-2026-21513, also rated at 8.8, affects MSHTML and allows remote attackers to bypass execution prompts through malicious code in HTML or shortcut files. CVE-2026-21514 impacts Microsoft Word and enables adversaries to disable OLE mitigations, posing risks through document-based attacks. Two local privilege escalation vulnerabilities are CVE-2026-21519 in Desktop Window Manager and CVE-2026-21533 in Windows Remote Desktop Services, with CVSS scores of 7.8. CVE-2026-21525 is a denial-of-service vulnerability in Remote Access Connection Manager. The update includes 53 additional vulnerabilities across various Microsoft products and services, with CVE-2026-21531 in Azure SDK rated at 9.8 and CVE-2026-20841 affecting Windows Notepad rated at 8.8. The cumulative update for Windows 11 (KB5077181) also includes enhancements and resolves WPA3 Wi-Fi connectivity issues. Microsoft reminded users of the June 2026 expiration of Secure Boot certificates, which requires timely updates to ensure secure booting. Users can install the updates via Windows Update.

Why Windows 11 feels slower than Windows 10—and why it’s not just in your head

Windows 11 features a modern architecture with advanced schedulers and SSD support, but many users experience sluggishness, with delays in menus and dialog boxes. This perception of reduced responsiveness compared to Windows 10 has been linked to the use of XAML, which modernizes traditional desktop components but introduces performance issues due to added abstraction layers. Disabling animations does not resolve the delays, which are attributed to XAML's reliance on GPU acceleration for simple tasks, leading to inefficiencies. The cumulative effect of these micro-delays, measured in milliseconds, contributes to an overall feeling of sluggishness, regardless of high-end hardware. Microsoft's design choices prioritize visual consistency and modern UI technology, resulting in trade-offs in everyday responsiveness. The slower perception of Windows 11 compared to Windows 10 is rooted in these deliberate technical decisions.

Already my favorite RTS this year, Tempest Rising is going full Command and Conquer by adding superweapons

The upcoming update for Tempest Rising will introduce two new superweapons: the Drone Strike Station for the Global Defense Force (GDF) and the Excavator Platform for the Tempest Dynasty. The Drone Strike Station allows players to call in orbital strikes and deploy nine tungsten Drone Turrets, while the Excavator Platform can create shockwaves, transport units underground, and restore health to infantry. These additions aim to enhance gameplay strategies for both factions.

Windows Graphics Vulnerabilities Allow Remote Attackers to Execute Arbitrary Code

Multiple vulnerabilities have been identified in Microsoft’s Graphics Device Interface (GDI), particularly related to Enhanced Metafile (EMF) formats, allowing potential remote code execution and information exfiltration. Key vulnerabilities include: - CVE-2025-30388: Rated Important with a CVSS score of 8.8, it involves out-of-bounds memory operations during processing of records, affecting Windows 10/11 and Office for Mac/Android. It allows attackers to read or write beyond allocated heap buffers. - CVE-2025-53766: Rated Critical with a CVSS score of 9.8, it permits remote code execution through out-of-bounds writes in the ScanOperation::AlphaDivide_sRGB function, affecting Windows 10/11 without requiring privileges. - CVE-2025-47984: Rated Important with a CVSS score of 7.5, it exploits a flaw in handling EMR_STARTDOC records, leading to information disclosure by exposing adjacent heap memory. Microsoft has released patches to address these vulnerabilities, and users are advised to apply them promptly. Recommendations include disabling EMF rendering in untrusted contexts and using sandboxed viewers for document access.

New Windows Graphics Vulnerabilities Expose Systems to Remote Code Execution Risks

Check Point Research (CPR) identified three vulnerabilities in Microsoft’s Graphics Device Interface (GDI): 1. CVE-2025-30388: Inadequate validation of clipping rectangles in EMF+ files can lead to heap corruption in GdiPlus.dll, allowing potential remote code execution. Microsoft patched this in May 2025 with version 10.0.26100.4061. 2. CVE-2025-53766: A critical flaw in GdiPlus.dll allows remote code execution without user interaction due to unallocated memory writes triggered by malformed EmfPlusDrawRects records. Microsoft addressed this in August 2025 with version 10.0.26100.4946. 3. CVE-2025-47984: This vulnerability, related to an earlier issue, involves improper handling of EMR_STARTDOC records in gdi32full.dll, leading to information disclosure. Microsoft fixed this in July 2025 with version 10.0.26100.4652. Microsoft released patches for these vulnerabilities during its Patch Tuesday updates in May, July, and August of 2025.
