There is no fixed version for RHEL:8 kernel-debug-core.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-debug-core package and not the kernel-debug-core package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
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().
