How to fix?

There is no fixed version for RHEL:10 python3-libmodulemd.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-libmodulemd package and not the python3-libmodulemd package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A flaw was found in libmodulemd. When parsing module metadata, the xmd field is converted into nested GVariant values through recursive YAML mapping and sequence helpers without a recursion-depth or node-count limit. An attacker who can supply crafted modulemd YAML with deeply nested xmd content can cause stack exhaustion or excessive resource consumption, resulting in a denial of service.
