[ Upstream commit c4ba329cabca7c839ab48fb58b5bcc2582951a48 ]

There is a small window during which the an URB may
remain active after disconnect has returned. If in that case
already freed memory may be accessed and executed.

The fix is to poison the URB befotre the work is flushed.

usb: misc: usb3503: make sure reset is low for at least 100us 2018-01-17T08:38:55+00:00 Stefan Agner stefan@agner.ch 2018-01-11T13:47:40+00:00 9f6ca0ea7a7a21963e73d69be42026e5c5954bc4 commit b8626f1dc29d3eee444bfaa92146ec7b291ef41c upstream. When using a GPIO which is high by default, and initialize the driver in USB Hub mode, initialization fails with: [ 111.757794] usb3503 0-0008: SP_ILOCK failed (-5) The reason seems to be that the chip is not properly reset. Probe does initialize reset low, however some lines later the code already set it back high, which is not long enouth. Make sure reset is asserted for at least 100us by inserting a delay after initializing the reset pin during probe.

usb: usbtest: fix NULL pointer dereference 2017-11-18T10:22:24+00:00 Alan Stern stern@rowland.harvard.edu 2017-09-29T14:54:24+00:00 8cf061d919e2102d0de0379bafea6cce1405d786 commit 7c80f9e4a588f1925b07134bb2e3689335f6c6d8 upstream. If the usbtest driver encounters a device with an IN bulk endpoint but no OUT bulk endpoint, it will try to dereference a NULL pointer (out->desc.bEndpointAddress).
