Google issues emergency Chrome update patching zero-day
Google released an emergency Chrome update on June 11, 2026 that patches 74 security vulnerabilities, including 17 rated critical and an actively exploited zero‑day (CVE‑2026‑11645). The update moves Windows and Linux builds to version 149.0.7827.102 and macOS to 149.0.7827.103. The flaw stems from Chrome’s JavaScript engine and could allow attackers using crafted HTML pages to execute code in the browser sandbox, read out‑of‑bounds memory or crash the browser. Google is rolling the fix out regionally and is withholding detailed technical information until most users have updated. Users can trigger the update manually via Chrome’s menu → Help → About Google Chrome.
Emergency security patch from a major platform (Google) addressing an actively exploited zero‑day affects web safety and the browser environment that underpins ad delivery and measurement; rapid adoption is important for the broader digital ecosystem.

BSI Warns: Update Chrome Now — 26 High‑Risk Flaws
The German Federal Office for Information Security (BSI) warns users to urgently update Google Chrome after Google patched 26 desktop vulnerabilities, many rated high risk. The BSI bulletin says attackers could exploit the flaws for actions including code execution, bypassing security protections, denial-of-service, information disclosure and data manipulation. Google has published patched Chrome versions: 146.0.7680.153/154 for macOS and Windows, and 146.0.7680.153 for Linux. Microsoft already released an updated Edge build (146.0.3856.72). Users can update via Chrome's Help → About menu, manually, or (on Windows) through the Microsoft Store if installed that way. Other Chromium-based browsers such as Opera and Brave are expected to follow with security updates.

Microsoft Patches Critical Zero-Day Bugs Targeting Windows Users
Microsoft released security updates fixing multiple zero-day vulnerabilities in Windows and Office that the company says are being actively exploited by hackers. At least two flaws enable one-click attacks — tricking a user into clicking a malicious link — and another allows compromise via a malicious Office file. Microsoft identified one flaw as CVE-2026-21510 in the Windows shell, affecting all supported Windows versions and able to bypass SmartScreen; another is CVE-2026-21513 in the MSHTML engine used for backward compatibility. Microsoft acknowledged input from Google’s Threat Intelligence Group and said exploit details have been published. Independent reporting (Brian Krebs) notes additional zero-days were patched. Security experts warned the bugs permit remote malware installation and high‑privilege silent execution, increasing risk of system compromise and ransomware.
