In the Linux kernel, the following vulnerability has been resolved:
hwmon: (ibmpex) Fix possible UAF when ibmpexregisterbmc() fails
Smatch report warning as follows:
drivers/hwmon/ibmpex.c:509 ibmpexregisterbmc() warn: '&data->list' not removed from list
If ibmpexfindsensors() fails in ibmpexregisterbmc(), data will be freed, but data->list will not be removed from driverdata.bmcdata, then list traversal may cause UAF.
Fix by removeing it from driverdata.bmcdata before free().
