Key notes

Yes, it’s that time of the month again, and Microsoft has released 55 security fixes, including patches that tackle zero-day vulnerabilities actively exploited in the wild.

The tech giant’s latest round of patches has fixes for six critical vulnerabilities, 15 remote code execution (RCE) bugs, information leaks, and elevation of privilege security flaws, as well as issues that could lead to spoofing and tampering.

Microsoft Azure, the Chromium-based Edge browser, Microsoft Office, and its associated products, Visual Studio, Exchange Server, Windows Kernel, and Windows Defender are some of the products targetted by the patches.
