When the payload\nlength is zero, each message type handler reads uninitialized payload\nand KMSAN detects this issue. The receipt of a packet with a zero-size\npayload is considered unexpected, and therefore, such packets should be\nsilently discarded.\n\nThis patch resolved this issue by checking payload size before calling\neach message type handler codes."
