{"schema":"threatline.record/2","record":{"id":"CVE-2026-98501","aliases":[],"summary":"HID: alps: fix use-after-free on input2 registration failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: alps: fix use-after-free on input2 registration failure\n\nalps_input_configured() stores data->input2 before calling\ninput_register_device().  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.","categories":["Operating
