> Microsoft patches two actively exploited vulnerabilities in February 2025 Patch Tuesday; immediate patching required.

The Japanese Information-technology Promotion Agency (IPA) has published an alert on Microsoft's February 2025 monthly security update cycle, released on 12 February 2025. The advisory flags two vulnerabilities, CVE-2025-21391 and CVE-2025-21418, which Microsoft has confirmed are being actively exploited in the wild. Successful exploitation could result in application crashes, system compromise, or full attacker control of affected computers. The advisory urges immediate application of security patches to mitigate the risk of expanding victimization.

The update cycle follows the standard monthly cadence; patches are typically deployed automatically via Windows Update. Organizations managing their own patch deployment should prioritize rapid rollout of these fixes. System reboots may be required after patch installation.
