Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Kernel allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in the Windows Kernel affects Windows 11 (24H2, 25H2, 26H1) and Windows Server 2025, where a race condition (CWE-362) in the synchronization of a shared kernel resource lets an authenticated low-privileged local user win a timing window to gain higher privileges. The CVSS 3.1 score is 7.8 with a scope-changed vector, the flaw was reported by Microsoft, and a patch is available. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
