Background
The Kernel is a crucial component of the Linux operating system that manages system resources and facilitates communication between hardware and software. It provides essential functionalities for the proper functioning of the system. The ngene subsystem within the Kernel is responsible for supporting the Next Generation TV (DVB) devices. This vulnerability specifically affects the ngene_command_config_free_buf() function within the ngene subsystem.
Vulnerability Detail
The ngene_command_config_free_buf() function in the ngene subsystem of the Kernel is susceptible to an out-of-bounds bug. This vulnerability was introduced in version v2.6.34 of the Kernel and has been present until version v5.13.6. An attacker could potentially exploit this bug to execute arbitrary code or cause a denial-of-service (DoS) condition. The bug occurs when the function attempts to free a buffer without properly validating its boundaries, leading to memory corruption and potential security risks.
