Executive Summary

This vulnerability is a possible memory leak in the Linux kernel's raspberrypi firmware component. Specifically, in the function rpi_firmware_probe(), if the call to mbox_request_channel() fails, the firmware object ('fw') is not properly freed because rpi_firmware_delete() is not called. This leads to a memory leak. The fix involves calling kfree() in the error path to ensure the memory is released.

Impact Analysis

The impact of this vulnerability is a potential memory leak in the Linux kernel when using the raspberrypi firmware. Over time, this could lead to increased memory usage and possibly system instability or crashes if the leak is significant and persistent.
