CVE-2026-93488

A flaw was found in Netty. SpdySessionHandler accepts an unlimited number of concurrent remote-initiated streams because localConcurrentStreams defaults to Integer.MAXVALUE and the handler provides no API to change it. A remote peer can open a SPDY connection and send a large number of SYNSTREAM frames with FLAGFIN=0, causing unbounded heap and direct memory allocation that can lead to JVM OutOfMemoryError and a denial of service.
