How to fix?

There is no fixed version for RHEL:7 postgresql-devel.

NVD Description

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

A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.
