{"id":"DEBIAN-CVE-2023-52475","details":"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-\u003econfig to cancel any in-progress requests upon device disconnection.
