In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> serial: arc_uart: fix of_iomap leak in `arc_serial_probe`<br /> <br /> Smatch reports:<br /> <br /> drivers/tty/serial/arc_uart.c:631 arc_serial_probe() warn:<br /> &amp;#39;port-&gt;membase&amp;#39; from of_iomap() not released on lines: 631.<br /> <br /> In arc_serial_probe(), if uart_add_one_port() fails,<br /> port-&gt;membase is not released, which would cause a resource leak.<br /> <br /> To fix this, I replace of_iomap with devm_platform_ioremap_resource.
