CVE-2026-54999: 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 Windows TCP/IP allows an unauthorized attacker to execute code over an adjacent network.
AI Analysis
Technical Summary
This vulnerability involves concurrent execution using a shared resource with improper synchronization (CWE-362) in the Windows TCP/IP implementation on Windows 10 Version 1607. The flaw allows an attacker on an adjacent network to execute arbitrary code remotely by exploiting a race condition. Microsoft has published an official fix addressing this issue. The CVSS 3.1 vector indicates the attack requires adjacent network access, no privileges or user interaction, and results in high confidentiality, integrity, and availability impacts.
Potential Impact
Successful exploitation allows remote code execution by an attacker on an adjacent network, potentially leading to full system compromise including confidentiality, integrity, and availability impacts.
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-2026-54999 to remediate this vulnerability.
