Microsoft published guidance for CVE-2026-24289, an Important severity Windows Kernel elevation of privilege vulnerability caused by CWE-416 (use-after-free). Microsoft scored the issue with CVSS 3.1: 7.8 (vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating exploitation requires local access with low attack complexity and low privileges, and could result in high impact to confidentiality, integrity, and availability if successfully exploited.

The Security Update Guide entry provides standard Microsoft consumption options (e.g., PowerShell, API, CSAF) for tracking and integrating the advisory into vulnerability management workflows. The two provided references are effectively duplicate MSRC pages for the same CVE (one localized under /en-US/) and do not add distinct technical details beyond the vulnerability classification and scoring.

Active Exploitation of Windows Kernel Privilege Escalation Vulnerability CVE-2025-62215

Microsoft has disclosed a critical elevation-of-privilege vulnerability in the Windows Kernel, tracked as CVE-2025-62215, which is being actively exploited in the wild. The flaw arises from a race condition and improper memory management, specifically a double-free scenario, allowing local attackers to escalate privileges to SYSTEM level. Exploitation requires an attacker to already have access to the system, but no user interaction is needed, and the attack can be automated. Microsoft has rated the vulnerability as Important, with a CVSS score of 7.0, and notes that all supported Windows 10 editions are affected, including those under Extended Security Updates (ESU). No workaround is available other than applying the official update, and immediate patching is strongly recommended. The vulnerability is classified under CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization) and CWE-415 (Double Free), making it a classic post-compromise privilege escalation vector. Attackers can exploit the timing-sensitive memory corruption path in the kernel to gain elevated access, disable security defenses, and move laterally within networks. The attack surface is particularly concerning in enterprise environments where multiple users share access, as any authenticated user can potentially trigger the exploit. Security experts warn that both targeted threat actors and ransomware operators may leverage this flaw to deepen their foothold after initial access, emphasizing the urgency of deploying the security update across all affected systems.
