Microsoft’s Patchy Past: November 2025 Fixes Critical Windows Kernel Bug
Microsoft’s November Patch Tuesday update is here, tackling 63 flaws, including a pesky zero-day Windows kernel bug. With four critical and 59 important vulnerabilities, it’s like a game show where everyone’s a winner—except the bugs. This month marks the first with Windows 10 out of the update loop.

Hot Take:
Microsoft’s Patch Tuesday for November 2025 is like a cybersecurity holiday where everyone gets delightful updates instead of gifts. With over 60 vulnerabilities fixed, it’s clear that Microsoft is trying to stay on the ‘nice’ list this year. But with a Kernel bug being actively exploited, it seems like some hackers are still trying to play the Grinch. Better luck next time, hackers—Microsoft’s elves are on the case!
Key Points:
- Microsoft addressed 63 vulnerabilities in their November 2025 Patch Tuesday updates.
- Four vulnerabilities were rated as Critical and 59 as Important.
- A Windows Kernel zero-day vulnerability was actively exploited and patched.
- The drop in the number of fixes is linked to Windows 10 no longer receiving updates.
- Microsoft also fixed an Office Remote Code Execution Vulnerability.
