Title
hwmon: (coretemp) Check for null before removing sysfs attrs
Summary
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. Don't pass that to
sysfs_remove_group() as that will crash in sysfs_remove_group().
[Shortened for readability]
