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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/53823e25793a97d07e6e98e0904bbf74cac8bc76","tags":[]},{"url":"https://git.kernel.org/stable/c/5e142adbbdc54afbd01fad476c91cded41d22594","tags":[]},{"url":"https://git.kernel.org/stable/c/72f4c2b7a48423c708f2c348585419a1b71ab04c","tags":[]},{"url":"https://git.kernel.org/stable/c/8a2c1bf209ba04cbd14153a771724bd5aa522fcd","tags":[]},{"url":"https://git.kernel.org/stable/c/9e992d59138fcfaa4bad7cc0750265b0a8bca100","tags":[]},{"url":"https://git.kernel.org/stable/c/ac866db277a4c73e84b4263773652e3aba326249","tags":[]},{"url":"https://git.kernel.org/stable/c/b97b5b66c93cb4aaf6358727a73fff880a774dfd","tags":[]},{"url":"https://git.kernel.org/stable/c/fd8223c53ad9553b2a349d2a40e19bbc6e60fc48","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
