Microsoft Outlook has a new ‘critical’ flaw that spreads malware easily

In a security alert, Microsft warned users how easy it is for hackers to distribute malware using their Outlook email client. Microsoft has already released a patch for the CVE-2025-21298 user-after-free vulnerability and urges users to apply it immediately.

Microsoft gave the vulnerability a severity score of 9.8 (critical) since it uses freed memory and corrupts valid data, or parcels out malware remotely. This bug is in the Windows Object Linking and Embedding (OLED) function, allowing you to embed and link to documents and other objects, such as adding an Excel chart to a Word document. It's so dangerous that you can become infected by previewing the specially crafted email.

Is Windows 11 acting up for you? This might be why

This year's big Windows 11 update, 24H2, started a phased rollout in October and just became available to more PCs yesterday, December 4, as spotted by Windows Latest. To check if your PC is ready for it, just head to the settings page and check for updates -- if an update is not there for download yet, you'll have to wait until later in the rollout process.

Getting new things first isn't always a good thing when it comes to software, however. It can take quite a while for a new Windows build to be announced as "stable," and 24H2 is far from earning that title at the moment.

Microsoft won’t back down on Windows 11’s biggest hurdle

Microsoft has reaffirmed that it will not lower the minimum hardware requirements for Windows 11, solidifying the need for a Trusted Platform Module (TPM) 2.0 and a compatible CPU. This decision leaves many older PCs ineligible for the upgrade. Microsoft emphasizes that these standards are vital for improved security and performance.

As per a recent blog post titled “TPM 2.0 – a necessity for a secure and future-proof Windows 11,” Microsoft reaffirmed its decision not to relax Windows 11’s strict hardware requirements. TPM 2.0 is a hardware-based security feature that protects sensitive data and ensures secure boot processes. Microsoft argues that such measures are nonnegotiable as the company continues to address rising cybersecurity threats. The minimum requirements include a list of approved CPUs, starting from AMD Ryzen 2000 and Intel 8th Gen processors, that offer advanced security features and better performance efficiency.
