Researchers from the University of Birmingham and Durham University discovered a vulnerability in consumer DDR4 and DDR5 memory chips, termed "Download more RAM," which allows attackers to misreport memory configuration, potentially doubling the perceived RAM. This manipulation enables unauthorized access to memory allocations, bypassing Windows' Virtualization-based Security (VBS) and Hypervisor-Enforced Code Integrity (HVCI), and disabling antivirus software. The vulnerability affects major manufacturers like Corsair, G.Skill, and ADATA, which collectively hold over 55% of the high-performance memory market. Microsoft has patched the vulnerability, cataloged as CVE-2026-23670, with a medium severity score of 5.7/10, in the April 2026 Patch Tuesday update. Corsair has introduced a feature to enable write protection on their memory modules, and other tools are available for additional protection.

‘This one just needs a script’: Researchers find ultimate Windows kill switch which can disable antivirus with almost no user interaction

Researchers have identified a significant vulnerability in consumer DDR4 and DDR5 memory modules, known as the “Download more RAM” flaw, which allows attackers to bypass advanced Windows security features, including Virtualization-Based Security (VBS) and Hypervisor Code Integrity (HVCI). This vulnerability enables the manipulation of configuration reports from RAM, misleading the system about its actual memory capacity, which can disable antivirus protections and allow the reintroduction of outdated drivers. The exploit can be executed via a single-click script, leading to security failures. Microsoft has released a patch for CVE‑2026‑23670 to enhance memory write protection against such exploits.

Microsoft Expands Windows Hello ESS to External Fingerprint Readers

Microsoft is integrating Windows Hello Enhanced Sign-in Security (ESS) with compatible external fingerprint readers, allowing passwordless sign-ins on a wider range of Windows 11 devices. This update enhances biometric authentication security by utilizing hardware-backed protections such as the Trusted Platform Module (TPM) and Virtualization-Based Security (VBS), which isolate sensitive biometric data from malware and unauthorized access. Previously, only devices with integrated fingerprint sensors could fully utilize ESS, but the recent update (KB5101684) enables external fingerprint readers to function within the ESS framework. The update is being rolled out for Windows 11 versions 25H2 and 24H2, and users can set up fingerprint authentication by connecting a compatible reader. This advancement aids IT administrators in implementing passwordless authentication while maintaining security protocols.

Not sure whether to use Windows Hello or Enhanced Sign‑in Security? This breakdown makes the choice easy

Microsoft will introduce Enhanced Sign-in Security (ESS) in the August 2026 update for Windows 11, allowing support for compatible external fingerprint readers. ESS aims to enhance the security of the authentication process rather than improve the accuracy of biometric recognition. Unlike standard Windows Hello, which processes biometric authentication through the operating system, ESS utilizes Virtualization-Based Security (VBS) and Trusted Platform Module (TPM) 2.0 to isolate sensitive operations in a protected environment. ESS-compatible fingerprint readers have dedicated secure processors, store templates internally, and communicate with the operating system via encrypted channels. Users can enable ESS by navigating to Settings > Accounts > Sign-in options on their devices. If a device does not support ESS, standard Windows Hello remains a robust authentication option.

Windows Hello vs. Enhanced Sign‑in Security: Which sign‑in method actually keeps your Windows 11 PC safer, and what’s the difference?

Microsoft will introduce Enhanced Sign-in Security (ESS) in the August 2026 update for Windows 11, which will support compatible external fingerprint readers. ESS aims to strengthen the authentication process against potential attacks by shifting processing to isolated, hardware-protected environments using Virtualization-Based Security (VBS) and TPM 2.0 technology. Unlike standard Windows Hello, which processes biometric authentication through the operating system, ESS-compatible devices perform more processing within the hardware itself, ensuring that only authentication results are sent to the OS. To enable ESS, users must navigate to Settings > Accounts > Sign-in options and follow prompts to set up their fingerprint recognition. Existing non-ESS biometric enrollments will be removed during the upgrade to ensure security.

After rewriting SQLite in Rust, Turso turns its sights on Postgres

Cloud database provider Turso is developing a Postgres-compatible implementation based on its SQLite-compatible database, which was created from scratch in Rust. CEO Glauber Costa believes Postgres can benefit from modernization for cloud-native applications. Turso's SQLite reimplementation, now called Turso, uses a virtual machine architecture that may eventually support other database frontends, including MySQL and Redis. The company initially forked SQLite into libSQL but later pivoted to a cloud service named Turso. They focused on a virtual machine architecture for their rewrite, which translates SQL queries into a custom bytecode language. Turso has developed a Postgres-compatible prototype named pgmicro, which aims to run existing applications with minimal modifications. The company is also working on a database-as-a-cloud service that will allow customers to use various database types on the Turso platform.
