Remediation
Red Hat statement
The Red Hat Enterprise Linux 7 kernel versions prior to Red Hat Enterprise Linux 7.7 GA kernel (version 3.10.0-1062 released via RHSA-2019:2029) were never affected by CVE-2019-14898 (ie the incomplete fix for CVE-2019-1159) because they never backported the incomplete fix for CVE-2019-11599 in the first place; CVE-2019-11599 was fixed there fully, ie backport consisted of both CVE-2019-11599 and CVE-2019-14898 patches.
Red Hat mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
