CVE-2026-71418

A flaw was found in Suricata, a network Intrusion Detection System, Intrusion Prevention System, and Network Security Monitoring engine. Its DNS-over-HTTP/2 processing incorrectly retains previously processed HTTP/2 DATA frame contents. A remote attacker can exploit this by sending multiple craft...

io.netty/netty-codec-http2: Netty: Denial of Service via HTTP/2 DATA frame memory leak

A flaw was found in Netty, a network application framework. A remote, unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP/2 DATA frames to applications that use Netty and have HTTP/2 content decompression enabled. This can lead to memory exhaustion, causing t...
