Elevation of Privilege (EoP) vulnerabilities accounted for 47.9% of the vulnerabilities patched this month, followed by Remote Code Execution (RCE) vulnerabilities at 17.4%.
CVE-2025-24052 and CVE-2025-24990 | Windows Agere Modem Driver Elevation of Privilege Vulnerabilities
CVE-2025-24052 and CVE-2025-24990 are EoP vulnerabilities in the third party Agere Modem driver. Both CVEs were assigned CVSSv3 scores of 7.8 and rated as important. Microsoft reports that CVE-2025-24990 has been exploited in the wild and CVE-2025-24052 was disclosed prior to a patch being made available. Successful exploitation would allow an attacker to gain administrator privileges on an affected system.
The ltmdm64.sys driver has historically shipped natively with supported Windows operating systems, but will no longer be supported following the October update. Microsoft notes, that ltmdm64.sys-dependent hardware will no longer work on Windows, and recommends users remove existing dependencies.
CVE-2025-59230 | Windows Remote Access Connection Manager Elevation of Privilege Vulnerability
CVE-2025-59230 is an EoP vulnerability affecting Windows Remote Access Connection Manager. According to Microsoft, this vulnerability has been exploited in the wild. It was assigned a CVSSv3 score of 7.8 and is rated as important. Exploitation of this vulnerability involves improper access control in Windows Remote Access Connection Manager and could allow a local attacker to gain SYSTEM privileges.
Including CVE-2025-59230, there have been 22 reported and patched vulnerabilities for the Windows Remote Access Connection Manager service (RasMan) since January 2022. CVE-2025-59230 is the first reported RasMan CVE to be exploited as a zero-day.
CVE-2025-59287 | Windows Server Update Service (WSUS) Remote Code Execution Vulnerability
CVE-2025-59287 is a RCE in the Windows Server Update Service (WSUS). It was assigned a CVSSv3 score of 9.8 and rated critical. It has been assessed as “Exploitation More Likely” according to Microsoft’s Exploitability Index. An attacker could exploit this vulnerability to gain RCE by sending a crafted event that leads to a deserialization of untrusted data.
This is just the third WSUS vulnerability patched as part of Microsoft Patch Tuesday since 2023, when Microsoft patched two WSUS EoP vulnerabilities (CVE-2023-32056, CVE-2023-35317) in the July 2023 Patch Tuesday, but the first RCE and to be assessed as more likely to be exploited.
CVE-2025-59227, CVE-2025-59234 | Microsoft Office Remote Code Execution Vulnerability
CVE-2025-59227 and CVE-2025-59234 are RCE vulnerabilities in Microsoft Office. Both vulnerabilities were assigned a CVSSv3 score of 7.8, rated critical and assessed as “Exploitation Less Likely.” An attacker could exploit these flaws through social engineering by sending the malicious Microsoft Office document file to an intended target. Successful exploitation would grant code execution privileges to the attacker.
Despite being flagged as “Less Likely” to be exploited, Microsoft notes that the Preview Pane is an attack vector for both CVEs, which means exploitation does not require the target to open the file.
CVE-2025-55680 | Windows Cloud Files Mini Filter Driver Elevation of Privilege Vulnerability
CVE-2025-55680 is an EoP vulnerability in the Windows Cloud Files Mini Filter Driver. It was assigned a CVSSv3 score of 7.8, rated important and assessed as “Exploitation More Likely.” A local, authenticated attacker would need to win a race condition in order to exploit this vulnerability. Successful exploitation would allow the attacker to elevate to SYSTEM privileges.
This is the 17th vulnerability in the Windows Cloud Files Mini Filter Driver since 2022. Microsoft patched two in 2022, six in 2023, six in 2024, and three in 2025. As part of its November 2023 Patch Tuesday release, Microsoft patched CVE-2023-36036, another EoP flaw, that was exploited in the wild as a zero-day.
