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

Executive Summary

This vulnerability is a resource leak in the Linux kernel's arc_uart serial driver. Specifically, in the function arc_serial_probe(), if the call to uart_add_one_port() fails, the memory resource mapped by of_iomap() (port->membase) is not released properly, causing a resource leak. The fix replaces of_iomap with devm_platform_ioremap_resource to ensure proper resource management.

Impact Analysis

The vulnerability can cause a resource leak in the kernel, which may lead to inefficient use of system resources or potential instability over time if the leak accumulates. However, it does not directly cause code execution or data corruption.
