How to fix?

There is no fixed version for Centos:7 kernel-kdump-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-kdump-devel package and not the kernel-kdump-devel package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

ovl: don't allow datadir only

In theory overlayfs could support upper layer directly referring to a data layer, but there's no current use case for this.

Originally, when data-only layers were introduced, this wasn't allowed, only introduced by the "datadir+" feature, but without actually handling this case, resulting in an Oops.

Fix by disallowing datadir without lowerdir.
