Official Description

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

HID: alps: fix NULL pointer dereference in alps_raw_event()

Commit ecfa6f34492c ("HID: Add HID_CLAIMED_INPUT guards in raw_event

callbacks missing them") attempted to fix up the HID drivers that had

missed the previous fix that was done in 2ff5baa9b527 ("HID: appleir:

Fix potential NULL dereference at raw event handle"), but the alps

driver was missed.

Fix this up by properly checking in the hid-alps driver that it had been

claimed correctly before attempting to process the raw event.
