Summary

- Microsoft has released a security patch to fix the vulnerability.
Microsoft recently addressed a significant security vulnerability within its Windows 11 operating system, specifically impacting the Notepad application. The company has issued a patch for a remote code execution flaw that was tied to the way Notepad handles Markdown formatting.
This vulnerability allowed for malicious actors to craft a dangerous link within a Markdown file.

The malicious code would run with the same permissions as the user who opened the file, posing a serious security risk.
Security researchers have confirmed that Microsoft's patch is effective. The company now displays a standard warning message to users before they click potentially unsafe links. It is strongly advised that all Windows 11 users verify their system is up-to-date to ensure this critical vulnerability has been resolved on their devices.
