Se descubrió un problema en net/ceph/messenger_v2.c en el kernel de Linux anterior a 6.4.5. Hay un error de firma de enteros, lo que provoca un desbordamiento del búfer y la ejecución remota de código a través de HELLO o uno de los frames AUTH. Esto ocurre debido a una longitud no confiable tomada de un paquete TCP en ceph_decode_32.
