The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream s390utils-cpuplugd package and not the s390utils-cpuplugd package as distributed by RHEL.
Calling curl_easy_pause() within the event-based CURLMOPT_SOCKETFUNCTION
callback triggers a use-after-free vulnerability, where libcurl attempts to
store a flag using a dangling struct pointer immediately after that pointer's
memory has been freed.
