Microsoft patches more than 1,400 flaws, including an exploited Windows zero-day
Microsoft has released fixes for more than 1,400 security vulnerabilities across Windows and other software, including an actively exploited Windows Shell flaw affecting Windows 10, Windows 11 and some server versions. At least 78 bugs are rated critical, while another .NET vulnerability was publicly disclosed before patching. The unusually large release reflects increased bug discovery, including Microsoft’s stated use of large language models, and creates testing and deployment strain for corporate security teams.
