CVE-2026-32159: CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in Microsoft Windows 10 Version 1809
Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Push Notifications allows an authorized attacker to elevate privileges locally.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-32159) involves a race condition (CWE-362) in the Windows Push Notifications component of Windows 10 Version 1809 (build 10.0.17763.0). Due to improper synchronization when accessing shared resources concurrently, an authorized local attacker could exploit this flaw to elevate their privileges on the affected system. Microsoft has published an official security update to remediate this issue.
Potential Impact
Successful exploitation allows an attacker with local access and low privileges to gain higher privileges, potentially leading to full system compromise. The vulnerability affects confidentiality, integrity, and availability as indicated by the CVSS vector (C:H/I:H/A:H). There are no reports of active exploitation in the wild.
Mitigation Recommendations
Apply the official security update provided by Microsoft as detailed in their advisory (https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-32159).
