In versions of netty-transport-sctp prior to 4.1.135.Final and 4.2.15.Final, for each non-complete SctpMessage fragment the handler does `fragments.put(streamId, Unpooled.wrappedBuffer(frag, byteBuf))`, wrapping the previous accumulator and the new slice into a *new* CompositeByteBuf every time. After N fragments the accumulator is an N-deep chain of composites, each holding references and component arrays; readableBytes()/getBytes() on the final buffer recurse N levels. There is no limit on N, on total bytes, or on the number of streamIdentifiers an attacker can open (each gets its own map entry). A peer that never sets the `complete` flag can grow this structure indefinitely from tiny 1-byte DATA chunks. Versions 4.1.135.Final and 4.2.15.Final patch the issue.</p> <p><strong>Affected:</strong> netty, Red Hat build of Apache Camel 4.18.1.P1 for Spring Boot 3.5.16, Red Hat Data Grid 8.6.2, Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7, Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 8, Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 9, Red Hat JBoss Enterprise Application Platform 8.1, Red Hat Enterprise Linux AI (RHEL AI) 3, Red Hat Fuse 7, Red Hat JBoss Enterprise Application Platform Expansion Pack and 1 more</p> <p>Netty is a network application framework for development of protocol servers and clients.
