GHSA-HF2G-6J7H-98WG klever-go: Unbounded goroutine spawn on direct-message ingress enables peer-driven DoS

Summary networkMessenger.directMessageHandler in network/p2p/libp2p/netMessenger.go spawns a fresh goroutine for every incoming direct message before the antiflood layer makes an admission decision. There is no semaphore, throttler, or bound on concurrent in-flight spawns. A single connected libp...

CVE-2026-32934

CoreDNS prior to version 1.14.3 is vulnerable: the DNS-over-QUIC (DoQ) server can spawn unbounded goroutines/memory growth when a remote client opens many QUIC streams and sends 1 byte per stream. With a full worker pool, CoreDNS still creates a goroutine per stream to wait for a worker token, an...
