DescriptionNVD

Buffer over-read in Remote Desktop Client allows an unauthorized attacker to disclose information over a network.

AnalysisAI

Information disclosure in the Windows Remote Desktop Client (mstsc/RDP client component) lets a remote attacker read memory beyond an intended buffer boundary, leaking potentially sensitive process data over the network. The flaw affects a broad span of supported Windows client and server releases from Windows Server 2012 through Windows 11 26H1 and Windows Server 2025. There is no public exploit identified at time of analysis, EPSS risk is modest (0.64%), and CISA's SSVC framework marks exploitation as 'none' — a patch is available from Microsoft.
