Information disclosure via uninitialized RDP client resource
Published Jul 14, 2026 · Updated Jul 14, 2026
Information disclosure in Microsoft Windows RDP Client allows remote attackers to read process data through a malicious RDP server. Microsoft identifies use of an uninitialized resource but has not disclosed the affected function, resource type, or data-return path. Exploitation requires a user to connect the RDP client to an attacker-controlled server; the reported consequence is disclosure only.
