Background
The pinctrl: samsung package is a component of the Linux Kernel that provides pin control and GPIO functionality for Samsung SoCs. It allows the configuration and management of pin banks, which are groups of pins with similar characteristics. These pin banks are used for various purposes, including controlling input/output operations and interfacing with external devices. However, a vulnerability has been identified in the package that involves the mishandling of pin bank references on error paths.
Vulnerability Detail
The vulnerability in the pinctrl: samsung package occurs when pin banks are not properly released in certain error scenarios. This can lead to resource leaks and potential memory corruption issues. An attacker who can trigger these error paths may be able to exploit the vulnerability to gain elevated privileges, execute arbitrary code, or cause a denial-of-service condition. The vulnerability was introduced in version v3.8 of the Linux Kernel and has been fixed in version v5.17.2.
How To Fix
