CVE-2026-20814: CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in Microsoft Windows 10 Version 1607
Concurrent execution using shared resource with improper synchronization ('race condition') in Graphics Kernel allows an authorized attacker to elevate privileges locally.
AI Analysis
Technical Summary
This vulnerability involves a race condition (CWE-362) in the Graphics Kernel component of Windows 10 Version 1607. Improper synchronization during concurrent execution using shared resources can be exploited by an authorized local attacker to elevate privileges. The CVSS 3.1 vector indicates the attack requires local access with high attack complexity and low privileges, but results in high impact on confidentiality, integrity, and availability. The vulnerability is confirmed published and a patch is available from Microsoft.
Potential Impact
An authorized local attacker can exploit this race condition to gain elevated privileges on the affected system. This could lead to full system compromise including unauthorized access to sensitive data, modification of system files, and disruption of system availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
A patch is available for this vulnerability. It is recommended to apply the official Microsoft update for Windows 10 Version 1607 (build 10.0.14393.0) to remediate this issue. No additional mitigation steps are indicated by the vendor advisory.
