| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: uclogic: Fix user-memory-access bug in uclogic_params_ugee_v2_init_event_hooks()\n\nWhen CONFIG_HID_UCLOGIC=y and CONFIG_KUNIT_ALL_TESTS=y, launch kernel and\nthen the below user-memory-access bug occurs.\n\nIn hid_test_uclogic_params_cleanup_event_hooks(),it call\nuclogic_params_ugee_v2_init_event_hooks() with the first arg=NULL, so\nwhen it calls uclogic_params_ugee_v2_has_battery(), the hid_get_drvdata()\nwill access hdev->dev with hdev=NULL, which will cause below\nuser-memory-access.\n\nSo add a fake_device with quirks member and call hid_set_drvdata()\nto assign hdev->dev->driver_data which avoids the null-ptr-def bug\nfor drvdata->quirks in uclogic_params_ugee_v2_has_battery().
