Security readout for executives and security teams
Plain-English summary
This flaw can let an unauthenticated network actor make affected Aardvark-dns stop answering other DNS requests. The business impact is service disruption: containers or hosts that depend on this DNS service may fail name resolution until the condition is cleared or fixed.
Executive priority
Prioritize remediation for RHEL 9 or container environments where Aardvark-dns is reachable by workloads or networks outside a tight trust boundary. This is not described as data theft, but DNS outage can quickly interrupt dependent applications.
Technical view
Aardvark-dns processes TCP DNS queries serially. A TCP client that keeps a connection open can block processing, causing other DNS queries to time out. The CVSS 3.1 score is 7.5, with network access, low complexity, no privileges, no user interaction, and high availability impact.
Likely exposure
Exposure is most relevant where affected containers/aardvark-dns versions 1.12.0 or 1.12.1, or Red Hat Enterprise Linux 9 aardvark-dns package 2:1.14.0-1.el9, are reachable by untrusted or semi-trusted network clients.
Exploitation context
The bundle does not show CISA KEV listing or any cited evidence of active exploitation. The described attack condition is simple: maintaining a TCP DNS connection can deny service to legitimate queries, but no weaponized exploit status is provided.
Researcher notes
Evidence supports a resource-consumption denial of service, CWE-400, caused by serial TCP query handling. The affected matrix is narrow in the provided bundle, with several Red Hat products marked unaffected. Public exploitation evidence is not present in the supplied sources.
Mitigation direction
- Apply Red Hat advisory RHSA-2025:7094 updates where applicable.
- Check the Red Hat CVE page for current fixed package guidance.
- Review upstream issue 500 and pull request 503 for project fix status.
- Restrict access to Aardvark-dns TCP service to trusted networks where feasible.
- Monitor for DNS timeout spikes until patched.
Validation and detection
- Inventory hosts and container platforms running aardvark-dns.
- Compare installed aardvark-dns versions against the affected entries.
- Confirm whether RHEL 9 systems have received RHSA-2025:7094 updates.
- Check DNS service metrics for increased timeouts or stalled TCP sessions.
- Verify listed unaffected platforms are not misclassified in asset records.
