There is no fixed version for Centos:7 libblkid.

NVD Description

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

An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file. NOTE: this is unexploitable in GNU C Library environments, and possibly in all realistic environments.
