Background
The Kernel is a critical component of the Linux operating system that manages communication between hardware and software. It provides essential functions and services to enable the proper functioning of the system. The ab8500 power supply driver is responsible for managing power-related operations on devices that use the ab8500 power management chip. This vulnerability specifically affects the ab8500_fg_sysfs_init function in the ab8500 power supply driver.
Vulnerability Detail
The ab8500_fg_sysfs_init function in the ab8500 power supply driver in the Kernel suffers from a memory leak issue. This vulnerability was introduced in version v4.9 of the Kernel by commit 8c0984e5a75337df513047ec92a6c09d78e3e5cd and fixed in version v5.15.33 by commit ffb8e92b4cef92bd25563cf3d8b4489eb22bc61f. When the ab8500_fg_sysfs_init function is called, it may allocate memory but fail to release it, leading to a memory leak. An attacker could potentially exploit this vulnerability to exhaust system memory resources, resulting in a denial-of-service condition or other unpredictable behavior.
