How to fix?

There is no fixed version for Centos:6 kernel-kdump.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-kdump package and not the kernel-kdump package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.15.15 does not always initialize the crc32c checksum driver, which allows attackers to cause a denial of service (ext4_xattr_inode_hash NULL pointer dereference and system crash) via a crafted ext4 image.
