Background
The Kernel package is a crucial component of the Linux operating system, responsible for managing the system's core functionality. It provides an interface between the hardware and software layers, allowing applications to communicate with the underlying hardware. The pinctrl subsystem within the Kernel package handles pin control and configuration for various devices. This vulnerability specifically affects the pinctrl: samsung module, which is responsible for managing pin banks on Samsung devices.
Vulnerability Detail
The vulnerability in the pinctrl: samsung module arises from a failure to properly handle error paths. On these error paths, references to pin banks are not properly dropped, leading to potential memory leaks and resource exhaustion. An attacker could potentially exploit this vulnerability to cause a denial-of-service condition or escalate privileges. The vulnerability was introduced in version v3.8 of the Linux Kernel and has been fixed in version v4.19.238.
