Q: Which packages are in scope for this update?

The update covers almalinux/bind, almalinux/bind-chroot, almalinux/bind-devel, almalinux/bind-dnssec-utils, almalinux/bind-doc, almalinux/bind-libs, almalinux/bind-license, and almalinux/bind-utils.

Q: What condition is associated with exploitation?

The issue is described as a denial of service through crafted DNSSEC responses. Systems running affected BIND components that process such responses are the relevant exposure area.
