How to fix?

Upgrade Centos:8 kernel-rt-modules to version 0:4.18.0-147.rt24.93.el8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-modules package and not the kernel-rt-modules package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

fs/ext4/extents.c in the Linux kernel through 5.1.2 does not zero out the unused memory region in the extent tree block, which might allow local users to obtain sensitive information by reading uninitialized data in the filesystem.
