CVE-2026-32086: 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 Function Discovery Service (fdwsd.dll) allows an authorized attacker to elevate privileges locally.
AI Analysis
Technical Summary
This vulnerability involves a race condition (CWE-362) in the Function Discovery Service component of Windows 10 Version 1607 (build 10.0.14393.0). Improper synchronization during concurrent execution of shared resources allows a local attacker with some privileges to elevate their privileges further. The CVSS 3.1 base score is 7.0, reflecting high impact on confidentiality, integrity, and availability, with attack vector limited to local access and requiring high attack complexity and low privileges. Microsoft has published an official fix to remediate this issue.
Potential Impact
An authorized local attacker can exploit this race condition to elevate their privileges on the affected Windows 10 system. This could lead to full system compromise, affecting confidentiality, integrity, and availability of the system. There are no known exploits in the wild at this time.
Mitigation Recommendations
An official fix is available from Microsoft. Users and administrators should apply the security update provided in the Microsoft advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-32086 to remediate this vulnerability.
