CVE-2026-24030
HIGH7.5EPSS 0.01%Published: 3/31/2026Modified: 4/28/2026
Description
An attacker might be able to trick DNSdist into allocating too much memory while processing DNS over QUIC or DNS over HTTP/3 payloads, resulting in a denial of service. In setups with a large quantity of memory available this usually results in an exception and the QUIC connection is properly closed, but in some cases the system might enter an out-of-memory state instead and terminate the process.
