Double Trouble: Sysadmins Brace for Microsoft’s Mega Patch Month
System administrators are pulling double duty after Microsoft dropped over 130 CVEs this month versus March’s Patch Tuesday. But don’t worry, only one zero-day bug crashed the party! Keep an eye on that CLFS vulnerability, though—it might just be the life of the post-compromise party.

Hot Take:
System administrators everywhere are collectively groaning as Microsoft drops a Patch Tuesday bombshell with over 130 CVEs to fix. But hey, at least there’s only one zero-day bug this time around, so they can sleep with one eye slightly less open!
Key Points:
- Microsoft has released fixes for over 130 CVEs, doubling the workload for system administrators compared to March.
- Only one zero-day vulnerability (CVE-2025-29824) is reported, a significant drop from March’s seven zero-days.
- The CVE-2025-29824 is an actively exploited elevation of privilege vulnerability in the Windows Common Log File System.
- Updates are currently available only for Windows Server and Windows 11; Windows 10 users have to wait.
- EoP vulnerabilities are the most common type fixed this month, totaling 49 out of the 130-plus CVEs.
