How to fix?

There is no fixed version for RHEL:8 xmlrpc-c-client.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xmlrpc-c-client package and not the xmlrpc-c-client package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

libexpat before 2.8.4 lacks handler call depth tracking with custom encoding callbacks. Thus, a use-after-free can occur. NOTE: this is similar to CVE-2026-50219, CVE-2026-56131 and CVE-2026-56412.
