In the Linux kernel, the following vulnerability has been resolved:
HID: steam: Rearrange teardown sequence
This fixes a narrow window during the teardown sequence where callbacks
could still be scheduled during cleanup that would then have a dangling
pointer to the now-freed steam struct.
This also puts work canceling for rumble and mode switch in
steam_unregister, as that shouldn't persist while the client hdev is open.
