Description Guilherme de Almeida Suckevicz 2026-07-30 14:18:33 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 Lokesh Mandvekar 2026-08-04 18:16:36 UTC 
Already fixed. Current builds (pack-0.40.8-1 across all Fedora releases) have golang.org/x/crypto v0.54.0, which meets the minimum required version v0.52.0 to fix CVE-2026-46597.
