Summary
UAF after pause in socket callback
Details

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.
