CVE-2026-35406: CWE-400: Uncontrolled Resource Consumption in containers aardvark-dns
CVE-2026-35406 is a medium severity vulnerability in aardvark-dns versions 1. 16. 0 through 1. 17. 0. It involves uncontrolled resource consumption where a truncated TCP DNS query followed by a connection reset causes the server to enter an unrecoverable infinite error loop at 100% CPU usage. This results in a denial of service condition. The issue is fixed in version 1. 17. 1.
