CVE-2026-59902 Netty: Memory Exhaustion in SctpMessageCompletionHandler

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...

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...
