Microsoft's latest patch cycle addresses a total of 107 vulnerabilities, including one zero-day vulnerability in Windows Kerberos. The update includes 13 critical vulnerabilities, nine of which are RCE vulnerabilities, three information disclosure vulnerabilities, and one elevation of privileges vulnerability. A publicly disclosed zero-day vulnerability allows an authenticated attacker to gain domain administrator privileges.
The August 2025 Patch Tuesday includes 107 security patches for Windows-related products. 13 critical vulnerabilities have been addressed, with 9 being classified as remote code execution (RCE) vulnerabilities. A publicly disclosed zero-day vulnerability in Windows Kerberos has been patched. The zero-day vulnerability, CVE-2025-53779, allows an authenticated attacker to gain domain administrator privileges.
Microsoft's August 2025 Patch Tuesday has been made available, and as per tradition, this update cycle brings a plethora of security patches for various Windows-related products. The most notable aspect of this patch cycle is the inclusion of one publicly disclosed zero-day vulnerability in Windows Kerberos.
The total number of vulnerabilities addressed by this patch cycle stands at 107, with 13 of them being categorized as critical, indicating that they have the potential to cause significant harm if exploited. Among these critical vulnerabilities, nine are classified as remote code execution (RCE) vulnerabilities, three are information disclosure vulnerabilities, and one is an elevation of privileges vulnerability.
The RCE vulnerabilities have the ability to allow attackers to execute arbitrary code on a system by exploiting specific flaws in Windows products. On the other hand, the information disclosure vulnerabilities may expose sensitive data or provide access to unauthorized areas of a system. The elevation of privileges vulnerability, however, can grant attackers elevated access levels within a system, which can further increase the potential damage caused.
One publicly disclosed zero-day vulnerability in this patch cycle is CVE-2025-53779 - Windows Kerberos Elevation of Privilege Vulnerability. This vulnerability allows an authenticated attacker to gain domain administrator privileges by exploiting flaws in the Windows Kerberos authentication mechanism. According to Microsoft, an authorized attacker needs elevated access to specific attributes (dMSA attributes) to exploit this flaw.
Yuval Gordon of Akamai is credited with discovering this zero-day vulnerability, which was published in May 2025 as a technical report.
In addition to the security patches for Windows products, other vendors have released their own security updates and advisories in August 2025. For instance, 7-Zip has released a security update for a path traversal flaw that could lead to RCE attacks. Adobe has also issued emergency updates for AEM Forms zero-days after publicly disclosed proof-of-concepts (PoCs) were released.
Fortinet, Google, Microsoft, Proton, SAP, Trend Micro, and WinRAR have also released their own security patches and advisories in this August 2025 Patch Tuesday cycle.
