How to fix?

There is no fixed version for RHEL:7 openshift/ose-rhel-coreos-8.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift/ose-rhel-coreos-8 package and not the openshift/ose-rhel-coreos-8 package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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

ecryptfs: reject too-small tag 70 packets

ecryptfs_parse_tag_70_packet() subtracts fixed metadata fields from the parsed packet body size to derive the encrypted filename size. A malformed packet with a body smaller than those fixed fields can underflow that size calculation.

Reject tag 70 packets before the subtraction unless the body contains the signature, cipher code, and at least one byte of encrypted filename data.
