How Microsoft Addressed These Threats

Zero-day vulnerabilities are security flaws that attackers exploit before developers can release a fix. In this Patch Tuesday, Microsoft addressed six such vulnerabilities:

CVE-2025-26633: A flaw in Microsoft Management Console that allows attackers to bypass protections by tricking users into opening malicious files or websites. Rated 7.8/10 in severity.

CVE-2025-24993: A memory bug in Windows enabling attackers to execute arbitrary code. Requires physical access to the system. Severity: 7.8/10.

CVE-2025-24991: A Windows flaw allowing attackers to access small portions of memory by tricking users into opening malicious disk image files. Severity: 5.5/10.

CVE-2025-24985: A math error in Windows’ file system that lets attackers run malicious code via harmful disk image files. Severity: 7.8/10.

CVE-2025-24984: A bug that accidentally writes sensitive information to log files, requiring physical access via a malicious USB drive. Severity: 4.6/10.

CVE-2025-24983: A timing vulnerability in Windows that grants full system control to attackers with physical access. Severity: 7.0/10.

Microsoft also addressed a seventh vulnerability, a remote code execution bug in Windows Access, which, while publicly disclosed, is not yet actively exploited.

Why These Updates Are Critical for Your Security?
