If registration fails, input_free_device()\nfrees the input device but data->input2 still points to the freed memory.\nalps_input_configured() calls hid_hw_open() before allocating input2, so\nURBs are already active and raw_event can fire during the failure window.\nA U1_SP_ABSOLUTE_REPORT_ID report arriving then causes u1_raw_event()\nto dereference the freed data->input2 -> use-after-free.\n\nFix by only storing input2 into drvdata after successful registration\nand adding a NULL guard in the raw_event path.","state":0,"publishedAt":"2026-10-18T15:16:46.205+00:00","modifiedAt":"2026-10-24T14:09:09.356+00:00","affected":[{"ecosystem":"Vendor
