Jinan USR IOT Technology’s USR‑W610 serial‑to‑Wi‑Fi/ Ethernet converter is the subject of a high‑severity Industrial Control Systems advisory that names four vulnerabilities (CVE‑2026‑25715, CVE‑2026‑24455, CVE‑2026‑26049, CVE‑2026‑26048) affecting firmware releases up to and including version...

Das U‑Boot contained a dangerous stack‑based buffer overflow in its NFS reply handling code — tracked as CVE‑2019‑14204 — that affects all upstream releases up through 2019.07 and can be triggered when a crafted NFS/UDP response is parsed by the bootloader’s nfs_handler helper...

Boot firmware that writes or reads pointers from untrusted non‑volatile variables is a high‑risk pattern — CVE‑2021‑28216 is a classic example: an EDK II (TianoCore) implementation reads the BootPerformanceTable pointer from an NVRAM variable during PEI (Pre‑EFI Initialization), and multiple...

Your PC’s ability to boot tomorrow depends on digital trust decisions made years ago — and those cryptographic certificates are about to reach their end-of-life in mid‑2026 unless your machine has already been updated. Background: why this matters now Secure Boot is the pre‑OS gatekeeper that...

Microsoft will begin delivering a coordinated refresh of Secure Boot certificates through Windows Update in March 2026, a multi‑stage effort designed to replace the aging 2011 trust anchors before they begin expiring in mid‑2026 and to preserve pre‑boot security and updateability across millions...

Microsoft has issued a coordinated warning: the original Secure Boot certificates that have underpinned Windows platform integrity since 2011 are reaching the end of their lifecycle, and a deliberate, ecosystem-wide refresh is required before mid‑2026 to avoid a progressive loss of...

IT administrators now have practical, fleet-scale ways to check whether Windows devices are carrying the updated Secure Boot certificate chain and whether they’re ready to accept the upcoming Secure Boot updates — a crucial capability as Microsoft and OEMs rotate the platform’s cryptographic...

Microsoft quietly closed the book on another long‑running Windows codebase this week — the Vista‑era Server 2008 line reached the absolute end of vendor updates after 18 years — even as a handful of high‑profile patches, rollbacks and component updates kept administrators busy: Microsoft shipped...
