NVD Description

In the Linux kernel, the following vulnerability has been resolved:

hwmon: (lm90) Only report alarms if driver is ready

Userspace can read sysfs attributes before driver registration is complete, immediately after devm_hwmon_device_register_with_info() has been called. At that time, data->hwmon_dev is not yet initialized. This can trigger a NULL pointer access since lm90_update_device() and with it lm90_update_alarms_locked() will be called. This call schedules report_work and lm90_report_alarms(), which passes the still-NULL data->hwmon_dev to hwmon_notify_event() and triggers a NULL pointer dereference.

Fix the problem by only scheduling the report and alert workers data->hwmon_dev is set.
