Description Srikanth Balasubramanian 2026-09-17 11:39:37 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.

A flaw in libcurl's handling of HTTP/2 Server Push streams, when the parent
handle is set to share connections with other handles, can lead to
use-after-free in the cleanup process.
Comment 1 Fabio Valentini 2026-09-17 12:09:52 UTC 
This package dynamically links system-provided libcurl, and does not include code from curl itself.
So the issue needs to be fixed in curl, and nothing can be done here.
