Adjacent code execution via undisclosed integer overflow
Published Jul 11, 2023 · Updated Jan 1, 2025
Integer overflow in the Layer-2 Bridge Network Driver in affected Microsoft Windows releases allows adjacent attackers to execute code. Microsoft identifies CWE-190 but has not disclosed the specific arithmetic operation, input field, or code path that overflows. Exploitation requires access to the same network segment and no authentication or user interaction, and successful exploitation grants arbitrary code execution on the target.

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.
