In the Linux kernel, the following vulnerability has been resolved: NTB: ntb_transport: Reject oversized TX buffers ntb_process_tx() handles an oversized buffer by calling tx_handler() with a NULL data pointer and returning success. ntb_netdev therefore neither frees the skb in its completion callback nor takes its enqueue error path, leaking it. Reject oversized buffers in ntb_transport_tx_enqueue() before acquiring a queue entry and return -EMSGSIZE. The caller retains ownership of the buffer, and the preceding netdev patch frees the skb when enqueue returns this permanent error.
