CVE-2023-52475

In the Linux kernel, the following vulnerability has been resolved: Input:
powermate - fix use-after-free in powermate_config_complete 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 usb_kill_urb() on pm->config to cancel any
in-progress requests upon device disconnection. [1]
