Description Jon Moroney 2026-07-06 19:36:45 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.

Hello,

The CVE-2026-9080 vulnerability impacts curl versions 8.13.0 --> 8.20.0.
Davix embeds curl v7.69.0 for EPEL8, whereas for all other platforms it uses the system-provided curl.

This vulnerability does not impact Davix.
Closing.

Cheers,
Mihai
