      "title": "platform/x86: classmate-laptop: Add missing NULL pointer checks",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86: classmate-laptop: Add missing NULL pointer checks\n\nIn a few places in the Classmate laptop driver, code using the accel\nobject may run before that object's address is stored in the driver\ndata of the input device using it.\n\nFor example, cmpc_accel_sensitivity_store_v4() is the \"show\" method\nof cmpc_accel_sensitivity_attr_v4 which is added in cmpc_accel_add_v4(),\nbefore calling dev_set_drvdata() for inputdev->dev.  If the sysfs\nattribute is accessed prematurely, the dev_get_drvdata(&inputdev->dev)\ncall in in cmpc_accel_sensitivity_store_v4() returns NULL which\nleads to a NULL pointer dereference going forward.\n\nMoreover, sysfs attributes using the input device are added before\ninitializing that device by cmpc_add_acpi_notify_device() and if one\nof them is accessed before running that function, a NULL pointer\ndereference will occur.\n\nFor example, cmpc_accel_sensitivity_attr_v4 is added before calling\ncmpc_add_acpi_notify_device() and if it is read prematurely, the\ndev_get_drvdata(&acpi->dev) call in cmpc_accel_sensitivity_show_v4()\nreturns NULL which leads to a NULL pointer dereference going forward.\n\nFix this by adding NULL pointer checks in all of the relevant places.",
