Background
The Kernel is a critical component of the Linux operating system that manages communication between software and hardware. It provides essential functions and services to enable the proper functioning of the system. The ngene driver is a media driver in the Kernel that supports the Next Generation Electronics (ngene) devices. These devices are used for capturing and processing audio and video data. However, a vulnerability has been discovered in the ngene_command_config_free_buf() function, which can lead to an out-of-bounds bug.
Vulnerability Detail
The ngene_command_config_free_buf() function in the ngene driver of the Kernel has an out-of-bounds bug. This vulnerability can be exploited by an attacker to manipulate memory beyond the allocated buffer, potentially leading to memory corruption, crashes, or even remote code execution. The bug was introduced in version v2.6.34 of the Kernel and has been fixed in version v4.9.277.
How To Fix
