Security Bulletin: Vulnerability in BIND (CVE-2026-1519) affects AIX/ VIOS.

Summary When a BIND 9 resolver performs DNSSEC validation on a maliciously crafted DNS zone, an attacker can trigger excessive NSEC3 iterations during insecure delegation validation. This causes the named process to consume excessive CPU resources, potentially making the resolver unavailable...
