How to fix?

There is no fixed version for RHEL:8 kernel-rt-core.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-core package and not the kernel-rt-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:

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.
