RHSA-2026:56999 PUBLISHED CVSS 7.5 HIGH

A flaw was found in aardvark-dns where a specially crafted TCP DNS query followed by a connection reset can trigger an infinite error loop, leading to 100% CPU usage and a denial of service. As aardvark-dns is only accessible via internal Podman networks, this issue can be exploited by a local container with network access.
