When all UART_NR slots are taken, it\nreturns -EBUSY with the fifo still allocated, but the probe error\npath only kfree()s the port, leaking the transmit fifo.\n\nFree the fifo in the failure path of sdio_uart_add_port() itself so\nthe function retains nothing on error.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
