Description
FreeRDP before 3.32.2 contains a use-after-free in the urbdrc USB redirection channel because FindChannelById returns a channel pointer without a reference and the control-channel close path does not take the device manager's loading_lock. A malicious RDP server can send a control-channel CLOSE_REQUEST while the client announces a USB device, freeing the channel before the announcement thread reads channel->Write and crashing the client.
