Mitigation checklist

Recommended fix / mitigation

To mitigate this issue, disable smartcard redirection when connecting to RDP servers using FreeRDP. This can typically be achieved by using the `--disable-smartcard` command-line option for `xfreerdp` or similar configuration in other FreeRDP-based clients. Disabling smartcard redirection may impact functionality that relies on smartcard authentication or access within the RDP session.
