Memory disclosure via out-of-bounds read
Published Aug 19, 2026 · Updated Aug 25, 2026
Out-of-bounds read in Remote Desktop Client in Microsoft Windows App before 11.3.9 on macOS allows remote attackers to read memory via session data. Public records do not identify the affected parser or routine; the disclosed mechanism is limited to the client reading past a buffer boundary while processing untrusted remote desktop data. Exploitation requires network access to deliver malicious session data and user interaction to open the connection, and the published impact is limited to information disclosure.
