SUSE CVE-2026-41417

Netty allows request-line validation to be bypassed when a DefaultHttpRequest or DefaultFullHttpRequest is created first and its URI is later changed via setUri. The constructors reject CRLF and whitespace characters that would break the start-line, but setUri does not apply the same validation...

GHSA-JFG9-48MV-9QGX Netty MQTT: Resource exhaustion in MqttDecoder

Impact The MQTT 5 header Properties section is parsed and buffered before any message size limit is applied. Specifically, in MqttDecoder, the decodeVariableHeader method is called before the bytesRemainingBeforeVariableHeader maxBytesInMessage check. The decodeVariableHeader can call other metho...
