Details

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().

Severity
7.8 (High)
