> Microsoft's April 2025 security update includes CVE-2025-29824, which is being exploited in the wild and requires immediate patching.

On April 9, 2025, Microsoft published its monthly security update addressing multiple vulnerabilities across its product line. The Japanese Information-technology Promotion Agency (IPA) issued a security alert highlighting CVE-2025-29824 as a vulnerability already being exploited in active attacks. Microsoft has confirmed in-the-wild exploitation of this flaw, indicating that attackers are actively weaponizing it. Successful exploitation could lead to application crashes, remote code execution, or system compromise. IPA strongly recommends immediate deployment of the security patches.

The IPA advisory indicates that affected organizations using Windows systems should prioritize applying these updates without delay. Windows Update automatically delivers security patches, though system restarts may be required following installation. Organizations with centralized patch management should refer to Microsoft's official monthly security bulletin and deploy patches across their infrastructure as quickly as possible to mitigate active exploitation risk.
