CVE-2025-24066: 
vulnerability analysis and mitigation

A heap-based buffer overflow vulnerability (CVE-2025-24066) was discovered in Windows Kernel-Mode Drivers. The vulnerability was disclosed on March 11, 2025, and affects various versions of Microsoft Windows operating systems. This security flaw allows an authorized attacker with local access to elevate their privileges on the affected system (NVD, CVE).

The vulnerability is classified as CWE-122 (Heap-based Buffer Overflow) and has received a CVSS v3.1 base score of 7.8 (High), with the following vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. This indicates that the vulnerability requires local access, low attack complexity, and low privileges, with no user interaction needed. The impact affects confidentiality, integrity, and availability, all rated as high (NVD, Rapid7).

The successful exploitation of this vulnerability can lead to complete compromise of system confidentiality, integrity, and availability through privilege elevation. As the vulnerability exists in the kernel-mode drivers, an attacker who successfully exploits this flaw could gain elevated system privileges and potentially take complete control of the affected system (NVD).

Microsoft has released security updates to address this vulnerability across multiple Windows versions, including Windows 10, Windows 11, and various Windows Server editions.
