Microsoft’s latest patch update, released in August 2025, has focused on addressing elevation-of-privilege (EoP) vulnerabilities that allow attackers to gain total system compromise. The update contains fixes for 111 unique Common Vulnerabilities and Exposures (CVEs), with 44 (39%) being EoP issues.
Among these, a maximum severity vulnerability in Azure OpenAI was already fully mitigated by Microsoft, while another publicly known Windows Kerberos EoP flaw, dubbed BadSuccessor, was patched. However, not all EoP vulnerabilities are high-priority concerns. For instance, the August update also includes patches for two vulnerabilities in Microsoft’s AI technologies: CVE-2025-53767 and CVE-2025-53773.
Other notable security issues include 34 remote code execution (RCE) vulnerabilities and 16 information disclosure flaws that could leak sensitive data. Two of these RCE vulnerabilities have near-maximum severity scores of 9.8 on the CVSS scale, highlighting their high-priority status. Organizations are advised to prioritize patching all instances of Microsoft products immediately, especially those with authentication bypasses, as attackers can exploit them to achieve full server compromise and data exfiltration.
Microsoft has designated 13 of the 111 new CVEs as being of “Critical” severity, emphasizing the importance of addressing these vulnerabilities promptly. As security researchers have warned, unvalidated input can execute commands with high-level privileges, leading to data compromise or complete server takeover.
