Microsoft had been slated to stop shipping updates for Windows 10 systems in October 2025, but ended up adding another year of free updates after considerable pushback. A few months ago, Microsoft <a href=\"https:\/\/www.windowscentral.com\/microsoft\/windows-10\/microsoft-quietly-extends-windows-10s-extra-security-updates-program-for-free-users-can-now-stay-on-windows-10-until-october-2027-securely\" rel=\"noopener\" target=\"_blank\">quietly extended that support<\/a> for another year (until October 2027).<span id=\"more-74474\"><\/span><\/p>\n<p>At least 78 of the flaws fixed this month are rated \u201ccritical,\u201d meaning they could be exploited with little or no action by the user, and most of those critical bugs allow an attacker to execute code of their choice on the vulnerable system.<\/p>\n<p>While Microsoft said there are no signs anyone is exploiting it yet, a security feature bypass in the .NET Framework (<a href=\"https:\/\/msrc.microsoft.com\/update-guide\/en-US\/advisory\/CVE-2026-108398\" rel=\"noopener\" target=\"_blank\">CVE-2026-108398<\/a>) was publicly disclosed prior to today, potentially giving attackers advance time to work out how to exploit the bug.<\/p>\n<p><strong>Satnam Narang<\/strong> at <strong>Tenable<\/strong> said the number of flaws fixed this month far surpasses the previous record-setting year 2020, when Microsoft patched 1,261 CVEs.<\/p>\n<p>\u201cWe\u2019ve now crossed the 4,000 CVE mark with two months left to go,\u201d he said.<\/p>\n<p>Microsoft credits large language models for the high volume of bug discovery, and presumably AI gets credit for many of the patches used to fix these flaw. Meanwhile, security experts have been warning that these unusually large patch volleys from Microsoft are placing extra strain on corporate security teams, which often have to test individual updates before deploying them across a network to ensure the fixes don\u2019t cause problems for other software.<\/p>\n<p><strong>Tyler Reguly<\/strong>, associate director of security research and development at <strong>Fortra<\/strong>, notes that just 26 Microsoft vulnerabilities appeared in the \u201cKnown Exploited Vulnerabilities\u201d (KEV) catalog maintained by the U.S. Cybersecurity &amp; Infrastructure Security Agency (CISA) so far this year, and security teams would do well to prioritize patching those 26 vulnerabilities first.<\/p>\n<p>\u201cSecurity leaders should focus on exploitable risk, and ask whether their teams have the clarity, capacity and support to act,\u201d Reguly said.<\/p>\n<p>Which vulnerabilities deserve the most scrutiny in your organization?
