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.
