Microsoft released its most current Patch Tuesday updates on August 12, 2025, resolving a remarkable total of 107 flaws across its entire ecosystem. Solutions for one openly known zero-day flaw that poses a severe threat to corporate Windows systems are included in this update.
In Microsoft’s August 2025 patch, each vulnerability category has a specific number of bugs, as mentioned below:
- 44 Elevation of Privilege Vulnerabilities
- 35 Remote Code Execution Vulnerabilities
- 18 Information Disclosure Vulnerabilities
- 4 Denial of Service Vulnerabilities
- 9 Spoofing Vulnerabilities
One of the most alarming problems in this release is a zero-day vulnerability discovered as CVE-2025-53779, which impacts Windows Kerberos. It was revealed before the patch was implemented, this vulnerability lets attackers with particular permissions raise their privileges to those of a domain administrator. The use of this vulnerability depends on how Windows handles particular properties in delegated Managed Service Accounts (dMSAs).
For businesses, this flaw could become a top-priority patch since it could offer total control over Active Directory environments. Under probe since May, Yuval Gordon of Akamai responsibly revealed it. Other important critical weaknesses fixed in Microsoft’s August 2025 patch include CVE-2025-50165, a remote code execution vulnerability inside the Windows Graphics Component that may be triggered simply by opening a malicious JPEG file.
CVE-2025-53766, found in GDI+, introduces a buffer overflow risk that could enable arbitrary code execution and was the factor of WinRAR 0-day vulnerability. Additional weaknesses in DirectX Graphics Kernel, MSMQ, and Microsoft Office Preview Pane increase the risk level, especially because some of these bugs do not call for user interaction or elevated privileges.
In some scenarios, there are some flaws that can be seen in mobile phones. Here are the classes of apps you need to delete right now to protect your data to save your iPhone and Android.
In Microsoft’s August 2025 Patch Tuesday, enterprise services have been fixed as well. Microsoft offered mitigations and silent patches for Azure services, including Copilot BizChat, Azure OpenAI, and parts of the Azure Portal, all of which had elevation-of-privilege and data leakage risk. Although Microsoft stated at the time of release that no active abuse of these flaws was known, the presence of a publicly known zero-day and numerous serious RCE vulnerabilities emphasizes the need for fast patch distribution.
