Description Jon Moroney 2026-03-20 17:55:21 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.
Comment 1 Ben Beasley 2026-03-22 07:37:25 UTC 
More information is available at https://www.cve.org/CVERecord?id=CVE-2026-33056. This flaw is fixed in version 0.4.45 of the tar crate. Updates for rust-tar-0.4.45 are in testing for all Fedora and EPEL branches, and buildroot overrides are active. However, since cosmic packages use vendored Rust crate dependencies, this package’s maintainers would need to fix this separately within the package’s dependency bundle.
