io.netty/netty-transport-sctp: Netty: Denial of Service via SCTP memory exhaustion

A flaw was found in Netty. The SctpMessageCompletionHandler component, which handles Stream Control Transmission Protocol SCTP messages, limits incomplete messages and fragment counts but does not properly limit maxBufferedBytes. An unauthenticated remote attacker could send specially crafted,...

CVE-2026-59902

Netty is an asynchronous, event-driven network application framework. Prior to 4.1.137.Final and 4.2.17.Final, io.netty.handler.codec.sctp.SctpMessageCompletionHandler limits incomplete messages and fragment counts but not maxBufferedBytes, allowing unauthenticated peers to exhaust memory with...

GHSA-2QJ4-MMR9-4V2F Netty: Memory Exhaustion in SctpMessageCompletionHandler

Summary SctpMessageCompletionHandler does not limit the total size of buffered fragments, allowing an unauthenticated attacker to cause an OutOfMemoryError by sending large SCTP fragments. Details io.netty.handler.codec.sctp.SctpMessageCompletionHandler buffers fragments for incomplete SCTP...

CVE-2026-59902

io.netty.handler.codec.sctp.SctpMessageCompletionHandler buffers SCTP fragments without enforcing a maxBufferedBytes limit. With defaults of 128 messages × 128 fragments × ~64KB chunks, an unauthenticated attacker can consume ~1GB per connection, causing OutOfMemoryError. Fixed in Netty 4.1.137.F...
