A vulnerability in the Linux kernel's network team driver was resolved involving improper handling of broadcast packets when no transmitable port is available. The function bc_transmit() sends the original socket buffer (skb) through the last transmitable port, but if no port is transmitable, it returns false without consuming the skb. However, team_xmit() incorrectly returns NETDEV_TX_OK, causing AF_PACKET sockets to retain the skb and its associated socket write-memory charge, potentially leading to resource leaks. The fix ensures the original skb is freed on the no-port path while maintaining existing drop accounting.
