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

hwmon: (ibmpex) Fix possible UAF when ibmpex_register_bmc() fails

Smatch report warning as follows:

drivers/hwmon/ibmpex.c:509 ibmpex_register_bmc() warn:
'&data->list' not removed from list

If ibmpex_find_sensors() fails in ibmpex_register_bmc(), data will
be freed, but data->list will not be removed from driver_data.bmc_data,
then list traversal may cause UAF.

Fix by removeing it from driver_data.bmc_data before free().
