Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Input: powermate - fix use-after-free in powermate_config_complete<br /> <br /> syzbot has found a use-after-free bug [1] in the powermate driver. This<br /> happens when the device is disconnected, which leads to a memory free from<br /> the powermate_device struct. When an asynchronous control message<br /> completes after the kfree and its callback is invoked, the lock does not<br /> exist anymore and hence the bug.<br /> <br /> Use usb_kill_urb() on pm-&gt;config to cancel any in-progress requests upon<br /> device disconnection.<br /> <br /> [1] https://syzkaller.appspot.com/bug?extid=0434ac83f907a1dbdd1e
