Microsoft's fifth Patch Tuesday of 2025 introduced fixes for five critical zero-day vulnerabilities, including elevation of privilege and memory corruption issues, all actively exploited in the wild. With a total of over 70 vulnerabilities addressed, the highlighted CVEs include dangerous weaknesses in key system components like the Windows Common Log File System Driver and the Scripting Engine. Experts warn of potential risks from these vulnerabilities, urging organizations to prioritize remediation to prevent escalated privileges and further exploitation.
With low complexity and minimal privileges needed, these flaws pose a serious risk, especially given the confirmed in-the-wild exploitation.
Attackers exploiting these vulnerabilities can escalate privileges to system level, granting them full control to run arbitrary code, install malware, modify data, or disable security protections.
