Microsoft Windows 11 Exploited 3 Times In 24 Hours By Zero-Day Hackers

At Pwn2Own Berlin, three teams demonstrated separate zero-day exploits against Windows 11.

The attacks used vulnerabilities such as privilege escalation, heap-based buffer overflow, use-after-free, and improper access control.

Microsoft has been notified through the event’s disclosure process and has 90 days to patch the flaws.

The findings highlight newly discovered security gaps in Windows 11 while limiting immediate real-world risk.
