There is no fixed version for RHEL:8 kernel-tools-libs.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-tools-libs package and not the kernel-tools-libs 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:
fbdev: efifb: Register sysfs groups through driver core
The driver core can register and cleanup sysfs groups already. Make use of that functionality to simplify the error handling and cleanup.
Also avoid a UAF race during unregistering where the sysctl attributes were usable after the info struct was freed.
