Io.netty:netty codec http3: Netty: Memory Exhaustion via HTTP/3 Reserved Frame Types (CVE-2026-56816)CVE-2026-56816 0 Netty's Http3FrameCodec in the io.netty:netty-codec-http3 library improperly trusts the payload length of HTTP/3 reserved frame types without validation, allowing an attacker to specify a very large payload length. This causes the server to buffer excessive data in memory, leading to memory exhaustion and a denial of service. The vulnerability arises because the payload length is read directly from the wire and can be up to Integer.MAX_VALUE, with no enforced maximum limit for reserved frames.
