CoreDNS DNS-over-QUIC Vulnerability (CVE-2025-47950)

748After Incident
CRITICAL-23
LEA604061125
A high-severity security vulnerability, CVE-2025-47950, has been discovered in CoreDNS, allowing remote attackers to exhaust server memory through DNS-over-QUIC (DoQ) stream amplification attacks. This can cause complete service outages in containerized environments, particularly in Kubernetes clusters. The vulnerability resides in the server_quic.go implementation, where unlimited goroutines are created for incoming QUIC streams without concurrency controls. Attackers can exploit this by opening numerous concurrent streams, leading to Out Of Memory (OOM) conditions. The flaw specifically targets deployments with the quic:// protocol enabled, posing a significant threat to organizations using DNS-over-QUIC for enhanced privacy and performance.
