Summary
Input: powermate - fix use-after-free in powermate_config_complete
Details

In the Linux kernel, the following vulnerability has been resolved:

Input: powermate - fix use-after-free in powermateconfigcomplete

syzbot has found a use-after-free bug [1] in the powermate driver. This happens when the device is disconnected, which leads to a memory free from the powermate_device struct. When an asynchronous control message completes after the kfree and its callback is invoked, the lock does not exist anymore and hence the bug.

Use usbkillurb() on pm->config to cancel any in-progress requests upon device disconnection.
