AnalysisAIv1 – Mar 12, 2026

Information disclosure and denial-of-service in TeamViewer DEX Client versions before 26.1 allows adjacent network attackers to trigger an out-of-bounds read via specially crafted packets, potentially leaking sensitive memory that could be leveraged to bypass ASLR protections. Affected Windows systems running the NomadBranch.exe content distribution service are vulnerable to attacks requiring only network proximity, with no authentication or user interaction needed.
