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.

Comment 1 Josh Stone 2026-03-11 16:30:11 UTC
We use the Rust "curl" crate to dynamically link to the system libcurl.so, so there's nothing for us to address on our own. We also ensure this is the case by removing the vendor/curl-sys*/curl/ source code during %prep.

The curl package only needs to fix the CVE itself.
