Description
In the Linux kernel, the following vulnerability has been resolved: media: uvcvideo: Fix memory leak in uvc_gpio_parse Previously the unit buffer was allocated before checking the IRQ for privacy GPIO. In case of error, the unit buffer was leaked. Allocate the unit buffer after the IRQ to avoid it. Addresses-Coverity-ID: 1474639 ("Resource leak")

Executive Summary

This vulnerability is a memory leak in the Linux kernel's uvcvideo driver related to the uvc_gpio_parse function. The issue occurred because the unit buffer was allocated before checking the IRQ for the privacy GPIO, and if there was an error, the allocated unit buffer was not freed, causing a memory leak. The fix involves allocating the unit buffer only after successfully checking the IRQ to prevent the leak.

Impact Analysis

This vulnerability can lead to a memory leak in the Linux kernel when using the uvcvideo driver. Over time, this could cause increased memory usage and potentially degrade system performance or stability, especially on systems that frequently interact with the affected driver.
