CWE-825  (opens in a new tab)

How to fix?

Upgrade RHEL:10 curl to version 0:8.21.0-0.1.hum1 or higher.
This issue was patched in RHSA-2026:29017.

NVD Description

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

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.
