Concurrent execution using shared resource with improper synchronization ('race condition') in Windows SMB allows an authorized attacker to elevate privileges over a network.
AnalysisAI
Elevation of privilege in the Windows SMB implementation allows an authenticated network attacker to win a race condition and gain higher privileges on affected systems, spanning Windows 10, Windows 11, and Windows Server 2012 through 2025. The flaw is a concurrency defect (CWE-362) reported by Microsoft with a vendor patch already released; there is no public exploit identified at time of analysis. Note a data conflict: the description and CVSS impacts describe privilege elevation with full confidentiality/integrity/availability impact, while the intelligence tags also label it 'Information Disclosure' — the CVSS vector should be treated as authoritative.
