Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
