Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Input: iforce - wake up after clearing IFORCE_XMIT_RUNNING flag<br /> <br /> syzbot is reporting hung task at __input_unregister_device() [1], for<br /> iforce_close() waiting at wait_event_interruptible() with dev-&gt;mutex held<br /> is blocking input_disconnect_device() from __input_unregister_device().<br /> <br /> It seems that the cause is simply that commit c2b27ef672992a20 ("Input:<br /> iforce - wait for command completion when closing the device") forgot to<br /> call wake_up() after clear_bit().<br /> <br /> Fix this problem by introducing a helper that calls clear_bit() followed<br /> by wake_up_all().
