Due to dns.podman search domain being removed, netavark may return external servers if a valid A/AAAA record is sent as a response. When creating a container with a given name, this name will be used as the hostname for the container itself, as the podman's search domain is not added anymore the container is using the host's resolv.conf, and the DNS resolver will try to look into the search domains contained on it. If one of the domains contain a name with the same hostname as the running container, the connection will forward to unexpected external servers."}],"affected":[{"versions":[{"status":"affected","version":"0","lessThan":"1.15.1","versionType":"semver"}],"packageName":"netavark","collectionURL":"https://github.com/containers/netavark","defaultStatus":"unaffected"},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 10","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"netavark","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:10"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"container-tools:rhel8/containers-common","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:8"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"container-tools:rhel8/netavark","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:8"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"netavark","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:9"]},{"vendor":"Red Hat","product":"Red Hat OpenShift Container Platform 4","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"rhcos","defaultStatus":"affected","cpes":["cpe:/a:redhat:openshift:4"]}],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2025-8283","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2383941","name":"RHBZ#2383941","tags":["issue-tracking","x_refsource_REDHAT"]},{"url":"https://github.com/advisories/GHSA-rpcf-rmh6-42xr"},{"url":"https://github.com/containers/netavark/releases/tag/v1.15.1"}],"datePublic":"2025-07-28T00:00:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-15","description":"External Control of System or Configuration Setting","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-15: External Control of System or Configuration Setting","workarounds":[{"lang":"en","value":"As a proactive mitigation, configure containers to have hostnames formatted as <name>.dns.podman.
