Summary
HID: hid-steam: Fix use-after-free when detaching device
Details

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

HID: hid-steam: Fix use-after-free when detaching device

When a hid-steam device is removed it must clean up the clienthdev used for intercepting hidraw access. This can lead to scheduling deferred work to reattach the input device. Though the cleanup cancels the deferred work, this was done before the clienthdev itself is cleaned up, so it gets rescheduled. This patch fixes the ordering to make sure the deferred work is properly canceled.
