Hello, I spent some time looking at: https://syzkaller.appspot.com/bug?id=c1b6aa968706d9380dcdb98a9f2c338071cc938c which does not yet report that it has been fixed. The problem seems to be in rsi_probe in drivers/net/wireless/rsi/rsi_91x_usb.c. This ends with the following code: status = rsi_rx_urb_submit(adapter, WLAN_EP); if (status) goto err1; if (adapter->priv->coex_mode > 1) { status = rsi_rx_urb_submit(adapter, BT_EP); if (status) goto err1; } return 0; err1: rsi_deinit_usb_interface(adapter); err: rsi_91x_deinit(adapter); The problem seems to be that the first call to rsi_rx_urb_submit succeeds, submitting an urb, and then theh second one fails. Both share adapter, which is used in rsi_rx_done_handler, invoked later as the callback provided with usb_submit_urb. But adapter, and in particular its rsi_dev field, are freed by the rsi_91x_deinit call due to the failure of the second call to rsi_rx_urb_submit. How should this be fixed? thanks, julia
