Microsoft Releases Emergency Windows 11 Update Following Patch Tuesday Bugs
Microsoft issued emergency Windows 11 update KB5129195 to fix Patch Tuesday regressions and fully close the CVE-2026-62721 privilege escalation flaw.
Microsoft shipped out-of-band cumulative update KB5129195 for Windows 11 24H2 and 25H2 (builds 26100.9457 and 26200.9457) after the September 8 Patch Tuesday rollup, which addressed over 960 CVEs including two actively exploited flaws, broke Remote Desktop Services, Hyper-V Plan9 folder sharing, and USB audio. The emergency release also strengthens the incomplete fix for CVE-2026-62721, an elevation-of-privilege flaw in the Windows User-Mode Power Service that could let a local attacker gain SYSTEM privileges. Companion patches cover Windows 11 26H1, Windows 10, and Windows Server. Some USB Audio Class 1.0 and AMD Radeon graphics issues remain unresolved.

Two critical Chrome flaws put users at risk on malicious websites
Google patched 26 Chrome flaws, including two critical use-after-frees and an actively exploited V8 sandbox escape (CVE-2026-85046); update to 152.0.7977.82/.83.
Chrome's desktop update fixes 26 security issues, including critical use-after-free flaws CVE-2026-84353 in Shared Tab Groups and CVE-2026-84352 in WebGL, both allowing code execution outside the browser sandbox via crafted HTML pages. Google subsequently patched CVE-2026-85046, a high-severity V8 JavaScript engine flaw with exploits already in the wild that enables arbitrary code execution inside the Chrome sandbox; HKCERT rates the overall risk as extremely high. Fixed versions are 152.0.7977.82/.83 on Windows and Mac and 152.0.7977.82 on Linux.
