Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Network File System allows an unauthorized attacker to execute code over a network.
AnalysisAI
Remote code execution in Microsoft's Windows Network File System (NFS) server role affects a broad range of Windows client and server builds from Windows Server 2012 through Windows Server 2025 and Windows 10/11. An unauthenticated network attacker who wins a race condition in a shared NFS resource can execute arbitrary code on the target. There is no public exploit identified at time of analysis and CISA SSVC rates exploitation as none; EPSS is low at 0.64% (47th percentile), consistent with the high attack complexity of racing the vulnerable code path.
