CVE-2025-24066
Published: 11 March 2025
Description
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Security Summary
CVE-2025-24066, published on 2025-03-11, is a heap-based buffer overflow vulnerability (CWE-122) affecting Windows Kernel-Mode Drivers. Assigned a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), it enables an authorized attacker to elevate privileges locally through improper bounds checking in kernel-mode components.
A local attacker with low privileges (PR:L) can exploit this vulnerability with low attack complexity (AC:L) and no user interaction required. Exploitation occurs via a heap-based buffer overflow, allowing the attacker to achieve high impacts on confidentiality, integrity, and availability, typically resulting in full privilege escalation from a standard user context to kernel-level access.
Microsoft's security update guide at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-24066 details available patches and recommended mitigations for addressing this vulnerability.
