CVE-2026-20808: CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in Microsoft Windows 11 Version 24H2
Concurrent execution using shared resource with improper synchronization ('race condition') in Printer Association Object allows an authorized attacker to elevate privileges locally.
AI Analysis
Technical Summary
This vulnerability involves a race condition (CWE-362) in the Printer Association Object component of Microsoft Windows 11 Version 24H2 (build 10.0.26100.0). Improper synchronization during concurrent execution of 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 no user interaction. The impact includes high confidentiality, integrity, and availability consequences. Microsoft has released a patch to remediate this vulnerability.
Potential Impact
An authorized local attacker can exploit this race condition to elevate privileges on the affected Windows 11 system. This could lead to full system compromise, affecting confidentiality, integrity, and availability of the system. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
A patch is available for this vulnerability. It is recommended to apply the official Microsoft update for Windows 11 Version 24H2 (build 10.0.26100.0) to remediate the race condition in the Printer Association Object. No additional mitigations are specified.
