Description Srikanth Balasubramanian 2026-07-31 04:21:18 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.

An incomplete guard in OpenVPN 2.6.0 through 2.6.20 and 2.7_alpha1 through 2.7.4 allows remote authenticated peers to trigger a use-after-free during TLS session promotion, potentially leading to a denial of service or memory leakage
Comment 1 Frank Lichtenheld 2026-08-03 11:29:38 UTC 
2.7.5 has been published to EPEL 10. EPEL 8 and 9 are not affected.
