Description Guilherme de Almeida Suckevicz 2026-07-30 14:15:55 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 incorrectly placed cast from bytes to int allowed for server-side panic in the AES-GCM packet decoder for well-crafted inputs.
Comment 1 Dave Dykstra 2026-07-31 13:19:37 UTC 
Apptainer does not use the crypto/ssh library so this vulnerability is not applicable
