USB: serial: mxuport: fix use-after-free in probe error path
The interface read and event URBs are submitted in attach, but were never explicitly unlinked by the driver. Instead the URBs would have been killed by usb-serial core on disconnect. In case of a late probe error (e.g. due to failed minor allocation), disconnect is never called and we could end up with active URBs for an unbound interface. This in turn could lead to deallocated memory being dereferenced in the completion callbacks. Fixes: ee467a1f2066 ("USB: serial: add Moxa UPORT 12XX/14XX/16XX driver") Cc: stable <stable@vger.kernel.org> # v3.14 Signed-off-by: Johan Hovold <johan@kernel.org> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
