Description

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

Security Summary

CVE-2025-24995, published on 2025-03-11, is a heap-based buffer overflow vulnerability (CWE-122) in the Kernel Streaming WOW Thunk Service Driver on Microsoft Windows systems. The issue carries 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), indicating high confidentiality, integrity, and availability impacts from local exploitation.

A local attacker with low privileges (PR:L) can exploit this vulnerability due to low attack complexity and no user interaction required. Successful exploitation allows privilege escalation, potentially granting the attacker higher-level access on the affected system.

Microsoft's advisory provides details on mitigation and available patches; see https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-24995 for guidance on updates and workarounds.

MITRE ATT&CK Enterprise Techniques

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Local heap buffer overflow in kernel driver directly enables privilege escalation from low-privileged context (T1068: Exploitation for Privilege Escalation).
