Service interruption via out-of-bounds NAT read
Published Oct 8, 2024 · Updated Aug 19, 2026
Out-of-bounds read in Windows NAT on affected Windows 10, Windows 11, and Windows Server builds allows remote attackers to interrupt the service. Microsoft identifies the weakness as an out-of-bounds read but has not published the affected function, malformed field, or operation that crosses the buffer boundary. Unauthenticated network traffic requires no user interaction; the documented consequence is availability loss, while the exact failure mode remains undisclosed.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
