{"id":"DEBIAN-CVE-2022-49010","details":"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-\u003ecore_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().
