Description Jon Moroney 2026-03-20 17:55:06 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 07:35:51 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 bpfman uses vendored Rust crate dependencies, its maintainers would need to fix this separately within the package’s dependency bundle.

Comment 2 Daniel Mellado 2026-03-22 09:40:53 UTC
Scratch build with the bumped version here https://koji.fedoraproject.org/koji/taskinfo?taskID=143600888, I'll update the repo after the build succeeds

Comment 3 Daniel Mellado 2026-03-22 10:25:23 UTC
Done, I'll wait for this to build https://koji.fedoraproject.org/koji/taskinfo?taskID=143601434 and then submit a package update for the latest build, + other f branches, tanks Ben!
