Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - In the Linux kernel, the following vulnerability has been resolved: hwmon: (coretemp) Check for null before removing sysfs attrs If coretemp_add_core() gets an error then pdata->core_data[indx] is already NULL and has been kfreed.
