CVE-2025-59227 [HIGH] CWE-416 Microsoft Office Remote Code Execution Vulnerability
Microsoft Office Remote Code Execution Vulnerability
Description: Use after free in Microsoft Office allows an unauthorized attacker to execute code locally.
FAQ: According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?
The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.
FAQ: According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?
An attacker must send a user a malicious Office file and convince them to open it.

CVE-2025-24990 [HIGH] Patch Tuesday, October 2025 ‘End of 10’ Edition
Microsoft today released software updates to plug a whopping 172 security holes in its Windows operating systems, including at least two vulnerabilities that are already being actively exploited. October’s Patch Tuesday also marks the final month that Microsoft will ship security updates for Windows 10 systems. If you’re running a Windows 10 PC and you’re unable or unwilling to migrate to Windows 11 , read on for other options.
The first zero-day bug addressed this month ( CVE-2025-24990 ) involves a third-party modem driver called Agere Modem that’s been bundled with Windows for the past two decades. Microsoft responded to active attacks on this flaw by completely removing the vulnerable driver from Windows.
The other zero-day is CVE-2025-59230 , an elevation of privilege vulnerability
