Description Jitendra Ahuja 2026-11-11 07:04:47 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 server can advertise a malformed unborn HEAD, causing unintended file writes during subsequent ref updates with the files ref backend.
