Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2023-7008
CWEhttps://cwe.mitre.org/data/definitions/300.html

A vulnerability was found in systemd-resolved. This issue may allow systemd-resolved to accept records of DNSSEC-signed domains even when they have no signature, allowing man-in-the-middles (or the upstream DNS resolver) to manipulate records.

Weakness

The product does not adequately verify the identity of actors at both ends of a communication channel, or does not adequately ensure the integrity of the channel, in a way that allows the channel to be accessed or influenced by an actor that is not an endpoint.
