So you have patched ffmpeg to fix a CVE in a tool (zmqsend) we don't even build? FEDORA-2026-bcaf0ddb2a has been pushed to the Fedora 44 testing repository. Soon you'll be able to install the update with the following command: `sudo dnf upgrade --enablerepo=updates-testing --refresh --advisory=FEDORA-2026-bcaf0ddb2a` You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2026-bcaf0ddb2a See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates.
