31255420263?profile=RESIZE_400xThis month’s patch bundle obliterates the software giant’s previous record set in July, when it released updates for at least 570 security vulnerabilities.  September’s Patch on 8 September 2026 brings the 2026 total to more than 2,600, more than twice Microsoft’s previous record-setting patch year in 2020 (1,245) and with three more months to go.[1]

There are two “zero-day” flaws fixed this month that are being actively exploited: both CVE-2026-81963 and CVE-2026-85880 allow an attacker to elev

Two Microsoft zero-days affecting its Defender antimalware suite are being actively exploited to trigger denial-of-service (DoS) states on unpatched Windows devices. The first flaw, tracked as CVE-2026-41091 (CVSS: 7.8), is a privilege escalation vulnerability impacting the Microsoft Malware Protection Engine versions 1.1.26030.3008 and earlier. This engine provides scanning, detection, and cleaning functions for Microsoft’s native security software.  The vulnerability arises from an improper li
