Microsoft has identified and addressed a critical security vulnerability in Windows 11 and Windows Server 2022. This flaw, if exploited, could potentially lead to permanent data loss on affected systems.
Who is Affected?
The vulnerability primarily impacts devices running Windows 11 and utilizing recent Intel or AMD processors. Here’s a breakdown:
- Intel: Systems with Ice Lake or later CPUs (including Alder Lake and Raptor Lake)
- AMD: Machines equipped with Ryzen 5000 processors and subsequent generations (including EPYC Milan and Ryzen 5000X3D)
The Root of the Problem
The issue lies within recently introduced code in Windows that interacts with VAES instructions on these newer processors. This creates a vulnerability that attackers could exploit to cause permanent data loss.
Patch Available, But With a Caveat
Microsoft released a patch on June 23rd, 2022, as part of the Windows 11 and Windows Server 2022 update. While this update addresses the security vulnerability, Microsoft acknowledges potential performance slowdowns for specific applications like BitLocker, Disk Throughput, and Transport Layer Security (TLS).
A Temporary Fix Until a Permanent Solution
A permanent fix is expected within a month. In the meantime, all users with Windows 11 and recent Intel or AMD processors are strongly encouraged to install the June 2022 update as a temporary security measure to mitigate the risk of data loss.
Staying Secure
It’s crucial to prioritize system updates to ensure your device remains protected against evolving security threats. While the current patch might cause slight performance drawbacks, it’s a necessary step to safeguard your data until a permanent solution arrives.
