CVE-2026-50045 on CTRL-OS 26.05

Aliases: CVE-2026-50045

Packages: unbound

Status: In Progress

Advisory Information

In NLnet Labs Unbound 1.22.0 up to and including 1.25.1, a single client query for a deeply nested name under a DNSSEC-signed parent can cause Unbound to send more upstream packets per client query than the configured 'max-global-quota'. This effectively bypasses a security configuration that limits upstream amplification traffic.
