What is CVE-2025-23028?

In Kubernetes clusters utilizing Cilium for DNS traffic proxying, a crafted DNS response from an external source can lead to the crashing of Cilium agents. This vulnerability affects versions 1.14.0 through 1.14.7, 1.15.0 through 1.15.11, and 1.16.0 through 1.16.4. While existing connections may remain active, new connections that depend on DNS resolution can be interrupted, causing disruptions in communication. Configuration changes cannot be applied until the affected agent restarts. Upgraded versions 1.14.18, 1.15.12, and 1.16.5 address this issue.
